Luanzheng Era

Dazhuo Era, or simply Dazhuo (Chinese: 大左; pinyin: Dà zuǒ) was a period of political violence, massacres, attacks, coup d'etats, and demonstrations in the Tseng Republic in the 1960s. The word 大左 means "big left" in Chinese and is called that in Tseng because most of the violence was committed by communists and socialists.

It started with the Longtan Coup on March 11, 1962, where PDP president Jack Lin was killed and disposed of by communists in the Longtan Complex in Longtan, Tseng City-Capital, and ended on December 23, 1968, when president Stephen Yang repealed Bill 643. Bill 643 was a law signed by Yong Ming-chun on July 13, 1958 that outlawed all far-left political parties in Tseng. That meant that all leftists, moderates and communists, were grouped into one party, the PDP. This led to severe internal conflict and eventually the far-left members of the party killed Jack Lin, who they felt was too "far-right".
