What efforts have been made by border towns in China to prevent the epidemic from being imported?

Border cities have been under pressure from China to resist the risk of external epidemic, especially Ruili, which has been closed for 160 days. These small cities have made the following efforts for epidemic prevention and control in China:

Sacrifice the economic development of the city and ensure that the cities in the country are within a safe range. For example, Ruili City, Yunnan Province has been closed for 162 days, and the local area is still under static management measures, so all personnel in Ruili should undergo health examination. You need to provide 48-hour nucleic acid certificate when you leave Ruili, but it is worth noting that the 48-hour nucleic acid certificate is divided into two 24-hour nucleic acid certificates. Only when two 24-hour nucleic acids are all proved negative can we travel from Ruili to all provinces in China.

The staff of border cities are stationed 24 hours a day in the border prevention and control zone. According to relevant news statistics, people from Southeast Asian countries sneak into China from China's border areas every year, which puts great pressure on China's epidemic prevention and control. Therefore, staff in some border cities will take turns to be on duty, and people will be stationed in areas where smuggling may occur 24 hours a day. Once someone is found to be smuggling, it will be forcibly repatriated, and at the same time, the nucleic acid test certificate and personal healthy temperature test will be done well.

The policy of nucleic acid detection in border cities is obviously different from other regions. If an individual wants to go to a border city for business reasons, he must first report to the city 24 hours in advance, and he needs to do a nucleic acid test after arriving in the border city. He should also record the time he stayed in this city, where he was going and what he was doing. All personnel from medium-risk areas should implement a 7-day quarantine policy, and they should also conduct two nucleic acid tests. If they come from high-risk areas, they should implement it.

Generally speaking, border cities have made great contributions to the prevention and control of epidemic situation in China.
