BEIJING - Since the 18th Communist Party of China (CPC) National Congress in 2012, the CPC Central Committee has dedicated itself to strict party governance.

In the past five years, the CPC Central Committee has tirelessly addressed "si feng," or "the four forms of decadence" -- formalism, bureaucratism, hedonism and extravagance.

By the end of 2016, 155,300 violations against the eight-point frugality code had been investigated, according to the CPC Central Commission for Discipline Inspection (CCDI).

Among the violations, 78.2 percent took place in 2013 and 2014, 15.1 percent took place in 2015, and 6.7 percent in 2016, representing a marked decrease each year.

The CPC has also stepped up its fight against corruption, targeting both high-ranking "tigers" and low-level "flies."

As of the end of 2016, the CCDI had investigated 240 centrally administered officials, punishing 223. Disciplinary inspection and supervision departments across the country registered 1.162 million cases of corruption, punishing 1.199 million people.

A total of 2,566 officials who fled overseas had been captured by the end of 2016, recovering 8.64 billion yuan (around 1.3 billion U.S. dollars). Of the top 100 fugitives listed on an Interpol red notice, 43 have been arrested.

In the past five years, the Party has also improved management and supervision of officials, adjusting the posts of 1,374 "naked officials" -- those above deputy department director level whose spouses and children reside abroad.

The CPC has also worked on Party rules. In the past five years, the CPC Central Committee has formulated or revised 88 Party regulations, 47 percent of the total of 188.
