On November 13, the Central Commission for Discipline Inspection and the National Supervisory Commission announced that Wang Zhonglin, former Party Secretary of Hubei Province, is under investigation for suspected serious violations of discipline and law. Wang Zhonglin took over as Party Secretary of Wuhan in February 2020, succeeding Ma Guoqiang, and was jokingly referred to by netizens as the "firefighter captain." Jiang Chaoliang, Wang Xiaodong, and Zhou Xianwang, who were known as the "Hubei F4" during the early stages of the pandemic, have previously been investigated.
