Editor's note：The CPC Central Committee holds a plenary session at least once a year in Beijing where it decides policies and decisions. The committee holds seven plenary sessions in five years.

The sixth plenary session of the 18th Central Committee of the Communist Party of China (CPC), held between Oct 24 and 27, discussed the issue of strengthening the Party's self-discipline. This was the Party's eighth "sixth plenary session" since the beginning of the reform and opening-up policy in 1978.

What the CPC did in these "sixth plenary sessions"? China Daily's archives reveal the picture.

1. The sixth plenary session of the 18th Central Committee of the CPC

Dates: Oct 24-27, 2016

Decision adopted: A regulation on the norms of political life within the Party, and a revision of an intra-Party supervision regulation

The two rules, with senior officials as the major supervision target, mark a shift from the initial shock-and-awe ousting of corrupt officials to perfecting the anti-graft regulations and mechanism.
