He said 8.26 million tests were performed by up to 17,000 inspectors in blocked areas of the city on Monday. “The huge number of medical staff, base staff, community workers and volunteers have shared the hard work at the forefront of preventing and controlling the epidemic, and we have to thank them,” Wu said. There have been growing signs of frustration on China’s social media, with dozens of residents flocking to the Weibo platform to seek help from relatives, with some having difficulty accessing medical services.
