Among the total 686 officials named, 66 were dismissed and 35 expelled from the ruling Communist Party of China (CPC), a statement from the party's Central Commission for Discipline Inspection (CCDI) said.
Seventy-eight of them were leading officials who failed to discipline their subordinates, it said, adding that most of the violations were excessive spending during holidays.
Other violations include accepting gifts, illegal use of public vehicles and extravagant celebrations.
Chinese government is conducting a massive anti-corruption campaign from the last few years in which thousands of officials, including some top leaders of the Communist Party and the military, have been punished.
Over 40 top ranking military officials including two Vice Chairmen of the Central Military Commission (CMC), the highest authority of the Chinese military forces, have been investigated for widespread corruption including allegations of selling top posts in the military for money.
