Big S "Sword Rain" plays a female killer, fragrant stills explode charming figure

  Directed by John Woo, the martial arts suspense love masterpiece "Sword Rain" has recently been exposed, and the pornographic female killer portrayed by Big S in the film has been exposed in advance. This is also the bold outflow of Big S’s first martial arts appearance.

  "Sword Rain" was jointly invested by Pony Pentium Film and Hong Kong Media Asia Variety. The high cost, the heavyweight production team, and the joining of 12 international big-name actors make it one of the most anticipated blockbusters. In addition, the appearance of several sexy actresses, including Big S, Lin Xilei, Wu Peici, and Jiang Yiyan, also added a bit of "spring" to this martial arts suspense love masterpiece. In the film, Big S plays a lustful female killer with agile shots and a pungent personality. One of her classic lines in the play has the taste of a modern avant-garde woman: "What’s good about a man, it’s better to be a girl, it’s more interesting to play with a man." In the exposed photos, Big S was lying on a bed, her body only wrapped in a piece of silk, and her perfect body was revealed to the fullest. A fat man beside her might be her "prey".

From Chongqing to Mount Everest, the proportion of intelligent driving is 91%, and the official announcement of Aouita has made NCA a success!

At the beginning of October, 2023, the HarmonyOS edition of Aouita 11 launched the "Intelligent Driving Everest Challenge". The total mileage is over 3,376 kilometers, and the altitude difference is as high as 5,000 meters. It took 9 days. Aouita 11 HarmonyOS Edition climbed six mountains with a height of more than 4,000 meters, crossed rivers and rivers, broke through the obstacles of complex terrain, and successfully reached the Everest Base Camp, with a total mileage of 91%.

Obviously, this 3,376-kilometer route from Chongqing to Mount Everest uses a smart driving without high-precision maps. Because at present, only six cities, namely Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou and Chongqing, have opened the pilot application of high-precision maps, and only Guangzhou, Shenzhen and Shanghai have relatively complete high-precision maps. The whole journey from Chongqing to Everest is almost out of the coverage of high-precision maps.

What is the specific performance of 91% of the smart driving?

This challenge began in the mountain city of Chongqing, where there are many cliffs, unpaved roads and thousands of turns, and the road conditions can be described as difficult and dangerous; In addition, unpredictable and complicated situations such as pedestrians or animals passing through, accidents occupying roads, construction road closures, falling rocks and landslides, and high-frequency rainy and foggy weather may occur along the way. These factors jointly construct the "hell-class" working condition of intelligent driving, which extremely tests the capacity limit of intelligent driving system.

Facing the "all-black tunnel", Aouita 11th HarmonyOS Edition has the strength to cope with the situation of occupation of roads, sudden change of light and shade, no lane line and slippery road surface, and has repeatedly taken the initiative to avoid lane change and take over the tunnel construction in the all-black environment of 3 kilometers, so as to truly see clearly, judge accurately and control stably.

Thanks to Huawei’s advanced intelligent driving system ADS 2.0, Aouita 11 has applied BEV fusion sensing algorithm and GOD network based on lidar, which has superior environmental awareness; Even if it passes through the 20-kilometer gravel road in Nujiang Gorge, or even the muddy road without the basic shape of the road at all, the intelligent driving system can still accurately identify the road edge and automatically plan the drivable area, which can be called "both good roads and bad roads can be opened".

In the face of the "Nujiang 72 Turn", the performance of the intelligent driving system is still steady and calm. With strong road perception accuracy and accurate dynamic target tracking ability, Aouita 11 HarmonyOS Edition can automatically slow down before entering the curve and speed up before leaving the curve like an "old driver", and can flexibly avoid the opposite car, and take over the continuous curve with a safe passage of 16 kilometers.

In response to all kinds of dynamic/static, standard/abnormal obstacles on the road, Aouita 11 HarmonyOS Edition has achieved 100% automatic avoidance, and achieved 100% safety with zero mistakes.

According to statistics, the average driving speed of Aouita 11 HarmonyOS version reached 62km/h, the driving power consumption per 100 km was 14.69kWh, and the battery life of "one box of electricity" was 535 km, showing the far-ahead intelligent driving ability and solid and reliable endurance level.

In September, Aouita said that its intelligent driving mileage exceeded 17 million kilometers. After this hellish test, the steady intelligent driving performance of Aouita 11th HarmonyOS Edition in the "Intelligent Driving Challenge" once again confirmed that it has become a map-free NCA, and it is capable and necessary to open it to users in Aouita. Therefore, on October 9th, Aouita announced that it would gradually open the map-free NCA, which would realize intelligent driving without relying on high-precision maps. The specific opening steps are as follows: No map NCA will complete the delivery according to the progress of 6 cities -16 cities-nationwide, and the intelligent driving function of expressway-urban area-parking will be realized nationwide by the end of 2023.

Li Pengcheng, vice president and chief marketing officer of Aouita Science and Technology, said: "From horse-drawn carriages to cars, from refueling to charging, from self-driving to intelligent driving, human travel modes have never stopped evolving; Today, Aouita, as a pioneer, has opened up a new way to enter Tibet, bringing users a more relaxed, labor-saving and green travel experience, which is also the greatest value of this intelligent driving of Mount Everest. "

The Sichuan-Tibet Highway in the "no-brainer’s zone" challenges the intelligent driving without a map, and achieves 91% of the intelligent driving results, which proves that Aouita’s intelligent driving NCA can be developed to users on a large scale, and also proves that Huawei’s ADS 2.0 intelligent driving strength is really superior, and the intelligent driving ability of Aouita 12 HarmonyOS version will also be a big selling point in the future.

They not only handed out leaflets to call New Gods: Nezha Reborn, but also cooperated with "New Nezha" Li Yunxiang and the third prince to dance the fairy dance, which jumped out of the unexpected magical effect and was very interesting.


The linkage between the two films has aroused many people’s feelings about White Snake: The Origin. Director Evonne released a heavy news on the spot, and the official will hold a series of commemorative activities on the second anniversary of the release of White Snake: The Origin, which makes people cheer that "there is an after-sale service after watching the second anniversary of the film, which is so delicious". At the same time, the cool and handsome "New Nezha" Li Yunxiang and the Third Prince also fascinated the audience, saying "See you in the cinema on the first day of the New Year".


Hand-painted posters of masked people are stunning, exposing and innovating.


New Gods: Nezha Reborn was built by the original crew of "White Snake: The Origin" for four years. The story took place 3000 years after the battle of deities. Nezha was reborn as a young motorcycle Li Yunxiang, and his enemies made a comeback in his previous life. When the deities were rearranged, the war was on the verge. Director Evonne explained the inheritance and innovation of the new series of deities at BW. He said that the light-chasing animation has always attached great importance to the innovation of the country. "The classic inheritance and innovation can coexist. We put the essence of the traditional Nezha story into modern elements and put it under the brand-new world outlook of oriental punk temperament, hoping to bring you a different feeling of the country."


A "invincible" hand-painted poster of the national tide wind was also officially announced at the scene. The poster was created by Lao Gui, the artistic director of Zhuiguang Animation. The mysterious masked man’s posture is cool, the suit wears a mask, and the motorcycle is equipped with a flag. Not only is the unruly character unobstructed, but it also brings a unique visual impact of combining traditional and modern elements with innovation. In the sense of seeing that the throttle is rushing to the new battle of sealing the gods, the national tide is also coming.


Director Evonne revealed: "The mysterious masked man is inextricably linked with Li Yunxiang, and he is also very cinematic." Yang Tianxiang was attracted by the visual style conveyed by the poster. On the spot, Amway said: "With such a shocking vision and story, I believe everyone will easily be brought into the world of the new list of gods when they walk into the cinema. Seeing the colors of the national tide, they must feel very good."


Management rules for loosening the network car in many places: lowering the entry threshold for vehicles and drivers.

  Since September this year, many cities, including Quanzhou, Fujian and Lanzhou, Gansu, have been exposed to have loosened the network car-sharing policy.

  Recently, Hangzhou, Zhejiang Province also held a legislative hearing on the Regulations of Hangzhou Municipality on the Administration of Passenger Taxi (Revised Draft). It is planned to bring the network car into the scope of passenger taxi management, and at the same time adjust the vehicle standards and driver access standards of the network car.

  Cheng Huiqiang, a researcher at the State Council Development Research Center, said in an interview with The Paper that the online car ride itself is one of the ways to deepen the reform of the taxi industry. The policy adjustment according to local conditions reflects the government’s open and scientific attitude towards emerging formats. Because there is still a time difference in the implementation of the network car policy in various places, the exploration of the first cities can provide reference for the subsequent cities to formulate local network car rules.

  In July 2016, the Interim Measures for the Administration of Online Booking Taxi Management Services was issued, which took effect on November 1 of the same year, and China took the lead in recognizing the legality of online car booking. Subsequently, many rules for the management of network car were issued, including many requirements for drivers’ household registration and operating vehicle standards.

  Detailed rules for the management of loosening the network car in some cities

  Since September this year, Quanzhou and Lanzhou have been exposed to the local version of the network car management rules. Hangzhou recently held a hearing on relevant policies.

  Judging from the changes in the rules of the above three cities, it mainly includes the following contents:

  1,Reduce the access standards for vehicle prices.

  Compared with the previous landing rules, Quanzhou, Lanzhou and Hangzhou have all set the lowest price standard for online car.

  Quanzhou originally required that the price of the online car should not be less than 150,000 yuan, which needs to be more than 50% higher than the mainstream taxi. It is now adjusted that the vehicle price shall not be less than 1.2 times the taxi price. Lanzhou City will adjust "the price of online car is more than 140,000" to 1.5 times that of mainstream taxis.

  According to the calculation of the media in the two places, thanks to this, the entry threshold for car prices in the two places has dropped by more than 30% to 50%.

  2. Lower the vehicle configuration standard.

  Previously, Quanzhou rules required that the network car must be equipped with a positioning device with driving record function and an emergency alarm device, and the Beidou satellite positioning system must be adopted. The new rules cancelled the designated system and only required the same technical conditions.

  Lanzhou is in the new regulations.The relevant standards of "the wheelbase of vehicles is 2700 mm", "the wheelbase of new energy vehicles is more than 2650 mm" and "providing wireless Internet access, mobile phone chargers, paper towels, umbrellas, etc. for passengers" have been deleted.

  The revised draft of Hangzhou simply cancels the original vehicle wheelbase and price standard, and treats the network car and taxi equally.

  3, lower the driver’s entry threshold.

  In the new regulations (drafts) of Lanzhou and Hangzhou, the city’s household registration or residence certificate will be obtained as the entry threshold for online car drivers.Deleted the time limit for obtaining the residence permit of this city for one year.

  4, reduce the difficulty of the exam.

  On September 8, the Ministry of Transport issued the Notice on Reforming the Work Related to the Qualification Examination for Taxi Drivers, and the number of questions in the question bank was reduced from 1,200 to 500, and the ratio of the number of questions in the question bank to the number of questions in the test paper did not exceed 10: 1.

  5, reduce administrative duplication of examination and approval.

  Originally, if the network car platform wants to settle in Quanzhou, it must submit an application to the Fujian transportation authorities, and the online service capability of the platform will be reviewed. Now it is adjusted to be verified by the registration place of the platform company to reduce duplicate certification.

  6, reduce administrative intervention in the market.

  According to the original rules of Quanzhou, the driver of the online car can’t "marry one woman and two" and can’t access two or more online car platforms at the same time. The new regulation cancels this regulation, and it is adjusted for the driver to sign an agreement with the platform vendor and act according to the agreement.

  It is worth noting that Hangzhou has also tried to incorporate the network car into the passenger taxi management system. To this end, Hangzhou tries its best to meet the existing taxi standards in terms of access to online car models, and proposes that the Hangzhou cruise taxi and online car exam will be implemented with "two exams in one" and "two certificates in one", so that drivers who pass the exam can not only open a car, but also drive a taxi to achieve interactive flow.

  The grey management state still exists.

  Regarding the adjustment of the new regulations on multi-network car-sharing, The Paper inquired about the opinions of many network car-sharing platforms, and generally responded that it is not convenient to say more now.

  According to the data of the Ministry of Transport, as of the end of July this year, 133 of the 338 cities at or above the prefecture level in China have issued detailed rules for the implementation of online car rental, and 86 are openly soliciting opinions.

  Some cities have been unable to introduce the detailed rules for the management of network car, and the slow progress of some network car platforms has led to the gray operation of network car drivers in many places.

  In August this year, Guizhou Metropolis Daily reported that Anshun City had been unable to introduce new regulations on online car rental. In the face of the special action of illegal operation in the whole city, more than 4,000 network cars in the city have become "illegal vehicles".

  At the same time, the number of cities that the network car platform company is allowed to land is not too much.

  In July this year, according to the People’s Daily, there are more than 130 online car platform companies in the current market. Up to now, 19 online car platform companies such as Didi Chuxing, Shenzhou Special Car, Shouqi Car and Caocao Special Car have obtained business licenses, and Didi Chuxing, Shenzhou Special Car, Shouqi Car, Yizhi and Caocao Special Car have obtained business licenses in 22, 33, 29, 8 and 13 cities respectively.

Is the IQ tax behind the "magic medicine" to delay myopia or is it really miraculous?

Have you ever seen a "magic medicine" in your parents’ circle?

An eye drop that claims to "delay myopia"

Some people buy it and some people go to online hospital to buy it.

There are even people who make it themselves.

Low concentration of atropine (0.01% atropine sulfate)

Is it an IQ tax or does it work wonders?

1. What is atropine?

Atropine is a classic old medicine. As an anticholinergic drug, it has a variety of pharmacological effects, which can help detoxify and relieve gastrointestinal spasm when pesticide poisoning occurs. Its clinical application in ophthalmology mainly includesAt present, the mydriasis of paralytic ciliary muscles is mostly used in optometry for children and adolescents.Slow mydriatic agentUse.

The earliest research on the prevention of myopia by atropine was conducted in Singapore. The research confirmed that low concentration of atropine (0.01% atropine sulfate) can inhibit the axial growth caused by myopia and delay the rapid progress of myopia. 

2. How hot is atropine?

Strabismus and pediatric ophthalmology in Xiamen Eye CenterXie RenyiThe deputy director said that every time he went to the outpatient clinic, at least three or five parents came to consult about the low-concentration atropine eye drops. There were many children who had used them for two or three years, mostly aged 7 to 9. An ophthalmologist in Xiamen has been using low-concentration atropine for her daughter for four months, and many "little glasses" among her classmates are using the same eye drops. According to foreign media reports, many parents all over the country went to Shanghai specially to prepare a low-concentration atropine eye drop for their children.

3、Atropine is not officially listed.

It should be noted that low concentration atropine eye drops have not been officially listed in mainland China.In fact, it is not easy to buy low concentration atropine eye drops. Many parents buy hospital preparations from China, Taiwan Province and Singapore, and some parents buy hospital preparations from individual hospitals in China through friends. These are not drugs that have been approved by the state for listing.

Deputy Director Xie Renyi introduced,A drug can only be listed as a new drug after the clinical verification stage is over and the expert review is passed.Although the current clinical evidence shows that low concentration of atropine eye drops has a certain effect on myopia prevention and control, domestic ophthalmologists have not yet reached a complete consensus on the long-term side effects and potential complications.

4. Can I use atropine?

Deputy Director Xie Renyi stressed: "This kind of eye drops is a kind of medicine, not suitable for everyone. It is most important for children to cultivate scientific eye habits and increase outdoor activities.This eye drop is an unlisted drug, so abuse is not recommended. "

5, blind abuse is not desirable

Xie Renyi, deputy director, said that many parents will buy atropine, and even some will make it themselves. not to mentionThere are also risks such as improper drug concentration, unstable ingredients and contamination of pathogens, which affect the comfort of eyes and cause damage, and may bring unexpected side effects.

In addition,People who are allergic to atropine are not suitable for use!For example, after use, symptoms such as blurred vision and photophobia may occur. Moreover, low concentration of atropine is not effective for all myopia patients, and the literature reports that there is a non-response rate of 10%-15%, that is, it does not work. In addition, some children will have allergic symptoms such as local itching and low fever.

Deputy Director Xie Renyi said that the prevention and control of myopia should be treated according to the actual situation of patients. Effective control is that myopia progresses within 50 degrees a year, and if it is above 75 degrees, other intervention methods or joint intervention can be considered. "Children who are using low concentrations of atropine must come to the hospital every three months." He said that this follow-up is to check the intraocular pressure, pupil, eye surface and eye adjustment function to ensure the health of medication.

if it isBlind use of glaucoma or other hidden diseases will aggravate the condition.. According to media reports, a 7-year-old child in Hangzhou is 100 degrees short-sighted. His father dripped low-concentration atropine every night, but when he went to check again, he found that the child’s intraocular pressure increased. The doctor said that if the intraocular pressure remained at a high level for a long time, it would damage the optic nerve.

In addition, Deputy Director Xie Renyi also reminded that although the concentration is low, it is stillSome children may have a rebound in myopia after stopping using this eye drop.For example, during the medication period, the original annual increase is controlled within 25 degrees. After stopping the drug, the degree may suddenly increase too fast in one year. If it exceeds 75 degrees in one year, you should consult a doctor immediately.

Scientific prevention and control of myopia

Want to play < combination boxing >

1. Pay attention to eye habits

1 Use less electronic products: Babies under 2 years old should not watch TV, computers, mobile phones, ipad and other electronic products. Babies over 2 years old should not use electronic products for more than 30 minutes every day.

② Follow the "20-20-20" eye protection rule when using eyes at close range.

Remember to keep "one punch, one foot and one inch" when writing and reading.

2. Do more outdoor sports.

Two hours of outdoor activities every day can effectively prevent myopia. Sunlight irradiation can stimulate the secretion of dopamine, which plays a positive role in preventing and controlling myopia.

3. Go to bed early and get enough sleep.

The results show that the later the time, the higher the incidence of myopia. It is best for children to go to bed at 8:30 in the evening and go to bed early to ensure adequate sleep time. Only after a good sleep can the muscles around the eyes (eyes) be completely relaxed, which is conducive to using the eyes the next day.
The American Academy of Sleep Medicine (AASM) gives the best sleep time for infants and adolescents:
4-12 months: 12-16 hours; 1-2 years old: 11-14 hours; 3-5 years old: 10-13 hours; 6-12 years old: 9-12 hours; 13-18: 8-10 hours.

4. Regular vision screening

6 months: A baby born normally should go to the hospital for refractive screening at about 6 months. About 3 years old: start teaching children to know the eye chart, and check their eyesight and diopter regularly every 6-12 months. 6-18 years old: It is recommended to check your eyesight every 6-12 months, and children with glasses should undergo mydriasis optometry every 12 months.

5. Orthokeratology mirror (OK mirror)

OK lens is a kind of hard and breathable contact lens with reverse geometric design. It only needs to be worn when sleeping at night to maintain clear vision during the day. Long-term wearing can delay the development of myopia.

China has become one of the 5G "first echelon" mobile phones, which will be available in the first half of next year.

  At the 2018 Mobile World Congress (MWC) in Barcelona, Spain, 5G has become one of the hottest keywords. Compared with the concept, framework and possibility of 5G discussed more in the past, a number of important breakthrough China 5G products were unveiled in this year’s conference, and some mature technologies and application scenarios were also displayed in the exhibition, which started the countdown to welcome the arrival of the 5G era.

According to reports, the new generation of 5G high and low frequency AAU released by ZTE supports the new air interface of 3GPP5G NR, supports the mainstream frequency band of 5G in the industry, and adopts a number of key technologies of 5G, which can meet the diverse scenarios and needs of 5G commercial deployment, and has been applied in domestic 5G testing and 5G testing of operators in many countries and regions.

  "China has become the most dazzling star on the 5G stage" and "the world looks at 5G, and 5G looks at China". Relevant professional analysis points out that China’s communication technology has gone through the following in the 2G era, the participation in the 3G era, and the breakthrough in the 4G era. In the 5G era, China has successfully entered the first echelon.

  pay close attention

  5G smartphones will be available in the first half of next year.

  In the terminal exhibition area of this conference, a conceptual mobile phone with ultra-high speed of 1.2Gbps also attracted a lot of attention. It is understood that this smart phone product, which is praised as "quasi-5G" or "pre-5G" by the industry, takes less than two seconds to download a high-definition movie.

  It is worth mentioning that during the current Mobile World Congress, China Mobile announced that it would jointly launch the "5G Terminal Pioneer Program" with 20 terminal industry partners around the world. The plan aims to launch the first batch of 5G terminals as soon as possible in the early stage of the industry, promote multi-party cooperation and jointly establish a mature 5G terminal industry ecology.

  According to reports, the plan has been widely responded and actively supported by the terminal industry, including 6 mainstream chip companies such as Qualcomm, Huawei, MediaTek, Ziguang Zhanrui, Intel and Samsung, and 10 mainstream terminal companies such as Huawei, OPPO, vivo, Xiaomi and Samsung.

  China Mobile expects that all parties will make concerted efforts to launch the first batch of 5G chips that meet the needs of operators before the end of 2018, and release the first batch of 5G pre-commercial terminals, including data terminals and smart phones, in the first half of 2019. The analysis believes that this also means that many brands of 5G mobile phones are expected to be available in the first half of next year.

  prospect

  There are still about two years before the real outbreak of 5 G.

  According to the plan of the Ministry of Industry and Information Technology, the three major domestic operators are expected to realize the scale commercialization of the fifth generation communication technology in 2020. According to the data, since 2013, China has taken the lead in launching the 5G test and R&D process. At present, China’s 5G commercialization process has been promoted in an orderly manner, and technology research and development testing has officially entered the third stage this year. The 5G field tests of the three major operators have been started one after another, and the pilot construction has been stepped up.

  At the same time, a number of recent developments that have emerged since the second half of last year show that 5G promotion is accelerating. Industry analysts believe that although there are still about two years before the real outbreak of 5G on the commercial timetable, the wrestling of the 5G industrial chain has been fully rolled out. The analysis also pointed out that with the commercialization process of 5G network, it will drive the development of applications such as car networking, Internet of Things, drones and cloud computing, which means that 5G will not only become a new round of development opportunities for the global communication industry, but also create opportunities for the rise of various emerging information technologies.

  The 5G economic report released by IHS, a market research organization, predicts that by 2035, 5G will create 12.3 trillion US dollars in global economic output and create 22 million jobs. Among them, China will have 9.5 million jobs, ranking first in the world, far exceeding the United States (3.4 million).

  The White Paper on the Economic and Social Impact of 5G issued by relevant institutions in China also pointed out that 5G, as a general-purpose technology, will open up a new era of mobile communication development, accelerate the process of economic and social digital transformation, and push the development of China’s digital economy to a new level. The white paper predicts that the direct output and indirect output driven by 5G will reach 6.3 trillion yuan and 10.6 trillion yuan respectively in 2030. In terms of direct output, according to the official commercialization of 5G in 2020, it is estimated that it will drive about 484 billion yuan of direct output in that year, and it will increase to 3.3 trillion yuan and 6.3 trillion yuan in 2025 and 2030 respectively, with a compound annual growth rate of 29% in the past ten years. In terms of indirect output, in 2020, 2025 and 2030, 5G will drive 1.2 trillion yuan, 6.3 trillion yuan and 10.6 trillion yuan respectively, with a compound annual growth rate of 24%.

  News memory

  5G can finish a 1080P movie in a few seconds.

  What is 5G? The relevant technical specifications of the International Telecommunication Union (ITU) have identified eight key capability indicators for 5G. According to reports, the peak rate of 5G in the future can reach 20Gbps. Other capability indicators include user experience data rate of 100Mbps, delay of 1 millisecond, connection density of 1 million devices per square kilometer, and traffic density of 10Mbps per square meter.

  "Compared with the current mainstream 4G communication, 5G brings the most intuitive benefits to users. In addition to improving the quality of calls, that is the transmission rate." Relevant professionals pointed out that the speed of 5G network can reach the level of Gbps or even tens of Gbps, which means that a movie in 1080P format can be downloaded in a few seconds. In addition, 5G communication also has the characteristics of low power consumption and high access, and has become an important foundation for the development of the Internet of Things.

  "For enterprises, 5G will create value for many fields, such as automobile transportation, energy/utility monitoring, security, finance, medical health, industry and agriculture, especially for large-scale and key application fields that require low latency. For consumers, the highlights of 5G services will be concentrated in two aspects: ultra-high-definition video applications and AR/VR applications. " According to the relevant report of GSMA, it is estimated that by 2025, 5G networks will be commercialized in 111 countries and regions around the world. After the early deployment, the 5G network will provide enhanced mobile broadband services with high speed, low delay, reliability and security.

  However, professionals also pointed out that in order to enjoy the convenience brought by 5G communication, consumers also need a terminal that supports it. At present, mobile phones in the hands of ordinary domestic users are not yet supported. "The arrival of the 5G era is bound to set off a new round of replacement boom." The above-mentioned person said.
