BEIJING, June 23 -- The disciplinary watchdog of the Communist Party of China (CPC) on Monday named and shamed five officials who violated principles of the CPC's campaign against undesirable work styles.

All five cases involved misconduct by graft-busters, who themselves are tasked with investigating corruption, according to a statement from the official website of the CPC's Central Commission for Discipline Inspection.

In one case, Cui Ruying, head of a township discipline inspection authority in Chongqing's Fuling District, was found to have received 107,250 yuan (17,226.8 U.S. dollars) as gifts at his father's birthday party.

Some 17,600 yuan of the total is from 77 of his colleagues who attended the birthday banquet.

Cui was given a "serious warning" and removed from his post.

In China, guests at birthday, wedding or funeral banquets usually give money to hosts as a gift. However, such a custom also risks being abused as an opportunity for bribery.

In another case, Duan Xinhong, head of the discipline inspection unit in Linfen People's Procuratorate in north China's Shanxi Province, was found to have received 52,400 yuan from 143 attendees of his father's funeral.

Duan was also accused of hiding the truth during investigation. He was removed from his Party position by Linfen City's discipline inspection commission.

As China's anti-corruption campaign picks up momentum, those charged with rooting out graft have also been facing closer scrutiny lately.

Earlier this year, the Commission for Political and Legal Affairs of the CPC Central Committee also publicized 10 cases of disciplinary or legal violations by police officers, judges and prosecutors.

China's leaders launched a campaign to clean up undesirable work styles such as formalism, bureaucracy, hedonism and extravagance in June, 2013.
