On this day, 32 years ago, on January 1, 1993 (December 9, 1992, the lunar calendar), a human trampled tragedy occurred in Lan Kwai Fong, Hong Kong, resulting in 21 deaths and 62 injuries. The Lan Kwai Fong tragedy was the rare and most serious crowd stampede accident in Hong Kong. It occurred on January 1, 1993 at Lan Kwai Fong and D'Aguilar Street in Central, resulting in 21 deaths and 62 injuries. Afterwards, the Governor of Hong Kong, Chris Patten, appointed the Justice of Justice Bill Bochig-king to independently investigate the incident. The Police Force adopted crowd control measures at subsequent major festival celebrations. The MTR opened overnight on New Year's Eve every year since December of the same year to prevent the tragedy from happening again. On New Year's Eve on December 31, 1992, a large number of citizens and tourists went to Lan Kwai Fong, Central, where there are many bars and restaurants to celebrate. Commercial radio set up a stage and giant balloons at the corner of Lan Kwai Fong to hold a New Year countdown pop concert. The live event was broadcast live on radio and television. The police deployed 118 police officers on the scene to maintain order. As the countdown to New Year's Day approached, nearly 20,000 people gathered at the scene. Many people poured out of bars and restaurants into the street to welcome the New Year. The scene began to get out of control. Some people sprayed spray ribbons and spray snowflakes, sprayed beer and soda, making the road very slippery. Many people walk to avoid being sprayed. Some people in the crowd even threw wine bottles and even bricks to burn newspapers. The tragedy occurred less than 10 minutes after the arrival of 1993. Due to different accounts of witnesses, the exact time cannot be determined. However, according to the records of the Hong Kong Fire Services Department, the first ambulance set out at 0:01 and arrived at the scene of the accident to pick up the injured and sent them to the hospital. However, the ambulance may have been called because of events before the accident. The second ambulance heading to the scene left at 0:08. It should have been called because of the accident. Therefore, the investigation report speculated that the accident started between 0:01 and 0:08. The location of the incident was on Tak Guilai Street, located below the intersection connecting Lan Kwai Fong and Ronghua Lane, and above the junction of Ho 'an Lane, a 17-meter-long slope road. After the countdown to the New Year ended, the crowd began to walk down D'Aguilar Street and left, filling the roads and sidewalks of D'Aguilar Street. Crowds continued to pour out of the streets on both sides of the intersection of D'Aguilar Street, and a few people tried to walk up D'Aguilar Street. First, several people in almost the same row in the crowd fell almost at the same time. The next person was squeezed by the crowd behind him and fell above the person who had fallen to the ground. If so, many people fell one after another, causing a domino effect. Until the people were stacked to a certain height, the squeezed people no longer fell above the pile of people, but pressed tightly against the pile of people in an upright position, forming what some witnesses called a "human wall." Senior Superintendent Zhang Zhichen estimated that there were five layers of people stacked together, and the number of people trapped inside the wall was at least 150 to 200. At this time, the people present still did not know that the accident had occurred, and people continued to walk west along Lan Kwai Fong to Tak Jili Street, increasing the pressure on the human wall. Later, someone was found injured at the scene, and the cries for help started to end before the crowd stopped squeezing. A large number of injured people were lying on both sides of the road, and tourists 'personal belongings were scattered all over the ground. In order to relieve the pressure on the human wall, Chief Inspector Kevin Clancy walked down D'Aguilar Street to Wellington Street, then ran up from Waidley to the stage, and listened to the host to broadcast to the crowd, instructing them to walk east along Lan Kwai Fong, and then up to Wyndham Street and leave. Senior Superintendent Zhang Zhichen ordered his men to form a line and make the crowd retreat along Daguilar Street. Zhang Zhichen estimated that the time it took to tear down the human wall and rescue the trapped people was about 7 to 10 minutes. Many injured people at the scene were lying on the ground waiting for rescue. There were no medical personnel stationed at the scene, so police officers on the scene initially provided first aid to the injured and called for off-duty medical staff for assistance. Many injured people have broken bones in their hands and feet, and some people have turned purple on their faces due to lack of oxygen. Due to the large number of injured, the ambulance workers and firefighters arriving at the scene were exhausted. An ambulance worker arrived on an ambulance electric bicycle equipped with a defibrillator. Later, Deng Zhaojian Hospital sent a mobile emergency team, consisting of a doctor and a nurse, to also arrive. Chief Superintendent Justin Cunningham, the commander of the Central District, said afterwards that the police deliberately kept a low profile to avoid damaging the atmosphere and affecting the business of businesses. He also pointed out that the police had expected the number of people on the scene, but the speed at which the crowd slipped and fell when the accident occurred exceeded the police's expectations. He also said that there were too many crowds and the police were unable to enter the crowd to rescue the injured five minutes after the incident. The police's crowd control measures that night were to observe on the spot, identify and isolate the perpetrators, protect those who were intoxicated and could not protect themselves from harm, and prevent crimes from occurring. The Lan Kwai Fong Chamber of Commerce pointed out that because Lan Kwai Fong is gradually becoming popular with the public, more and more people are gathering to celebrate the festival. The Chamber of Commerce is also worried that many of the celebrating crowd will be drunk minors. Therefore, during regular meetings with the police in the past two years, it has repeatedly suggested that crowd control should be carried out during the festival. However, the police responded that the street is a public place and the event is not a parade or demonstration, so crowd control cannot be carried out. The Chamber of Commerce first put forward this proposal on New Year's Eve in 1990, and the most recent one was in mid-December. Because more than 20,000 people gathered on Halloween before, the streets were overwhelmed.
