On April 15, a statement signed "Yang Hai, a volunteer from Pingyang Six Villages" was circulated on the Internet, allegedly, the author Yang Hai is the former secretary of the Party Committee of the Aerospace Plant, a representative of the Minhang District People's Congress, and a member of the Standing Committee. The author said in the statement that after more than a month of testing and lockdown management, what he saw was: more and more nucleic acids were being done, and there were more and more positive patients, but no one cared about analyzing and summarizing the causes of infection; The organization of the testing process and follow-up work was chaotic, the notice of almost every test was given very suddenly and temporarily, the information and data after the test were not transparent and accurate, the positive infected people could not be evacuated in time, and the Yangyang corridor was not arranged for professional disinfection; Many of the problems exposed are caused by the lack of integrity, foresight, uncoordinated work, and inadequacy of government agencies at all levels, and in the end, the problems are deposited again and again in the most basic residents' committees, resulting in a lot of unnecessary efforts and hard work; The feedback channels for grassroots opinions are not smooth, and many problems are fed back through channels such as neighborhood committees, hotlines, and people's congress deputies, but they cannot be answered. Therefore, Yang Hai said that until the above problems are not taken seriously and improved, he will no longer cooperate with the volunteer work of nucleic acid testing. After the statement was issued, local media in Minhang visited the community and published an article saying that "the volunteers are working too hard, complain", and the publisher of the statement, Yang Hai, is still doing volunteer work.
