Wang Dongxing
During the early stages of the Cultural Revolution, in 1966 and 1967, Luo Qingchang was initially named as a "black element" and endured persecution by the Red Guards, but very soon he managed to escape harm and return to his duties; this was almost unique among high-ranking CID officials, and probably had to do with Luo's friendship with Premier Zhou Enlai and Wang Dongxing; nearly all leading officials of the CID were purged between 1966 and 1970.
