The top disciplinary arm of the Communist Party of China (CPC) on Tuesday named and shamed officials who had broken regulations relating to righteous life and work styles.

The CPC Central Commission for Discipline Inspection (CCDI) released the names of officials involved in eight cases concerning the use of public funds for banquets; travel and entertainment; lavish funerals; and using official cars for personal activities, among others.

Officials ranged from local-government level to leaders of state-owned enterprises, the CCDI said in a statement, adding that punishments ranged from warnings to dismissals.

In one case, Dong Jun, mayor of Xi'an City in Shaanxi Province, was given a disciplinary warning because he had frequented a private club.

An eight-point rule was introduced at Political Bureau of the CPC Central Committee meeting at the end of 2012, to address bureaucracy,formalism and extravagance.

The CCDI has been publicizing these sorts of cases since April 2014. It has named officials implicated in over 2,000 cases since it began the campaign.

The disciplinary watchdog also warned officials against untoward behavior during the holidays, such as the upcoming May Day holiday and the Dragon Boat Festival.

Holidays usually see a rise in gift-giving, banquets, ceremonies and other violations in China. May Day holiday and the Dragon Boat Festival are three-day national holidays in May and June.
