What is the root cause of Zhengzhou "red team" incident? What is the cause and effect of this matter?

On June 15, 2022, many owners in Zhengzhou reported that their Yukang code turned red inexplicably and the nucleic acid test was negative, but it was listed as an entry person who was undergoing centralized or isolated medical observation at home. Even my own family members are accurately recruited. Through media investigation, it is found that, like the bank depositors exposed this time, most of these people who have been marked with red code are owners of some buildings that have stopped construction in Zhengzhou, Henan Province. That is to say, the red code incident is not a natural disaster, but a man-made disaster. In the first case, June 13, a woman wanted to get her money back from a rural bank in Henan, prepared nucleic acid in advance and reported the information. When the lady checked into the hotel, she told herself about the situation and found that her health code turned red inexplicably after eating. In the second case, many people say that people sit at home and the red code comes from the sky. Even the depositor in Beijing said that he would scan the code to register Zhengzhou's epidemic prevention information before departure, but his Beijing health code has always been green, and his travel itinerary only has Beijing. However, it is infuriating that the reason why these depositors are labeled as red team has nothing to do with the COVID-19 epidemic. The fundamental reason is that they have difficulty in withdrawing money from Henan rural banks, and some depositors know the progress of things. However, the police told depositors to legally defend their rights and not to gather. In other words, the root cause of this red code incident is that depositors who have difficulty withdrawing money from Henan rural banks have been labeled with red codes for no reason. Rural banks hope to prevent users from withdrawing money by attaching red team. The third was June 12. I took a bus to Zhengzhou. When scanning the code on the expressway, the health code suddenly changed to red team, and I was not allowed to get off the expressway. Even if I take the high-speed train to Zhengzhou, after scanning the code in high-speed railway station, I will immediately become red team, and I am not allowed to leave the station. Some personnel were repatriated, and those who did not want to be repatriated were quarantined 14 days. For the occurrence of this incident, Bian Xiao believes that the defensive purpose of the Health Law has passed, which is not in line with the legitimacy of the Health Law itself and violates the law. Secondly, it added some useless factors at this time, which is an abuse of power. And this unauthorized coding will also impact the credibility of the whole health code, and it will become more difficult to safeguard individual rights.
