An eight-part documentary, Corruption Fight is Always Underway, which hit the small screen less than a week before the Sixth Plenum of the 18th Central Committee of the Communist Party of China began in Beijing on Monday, has put the focus back on the fight against corruption.

Co-produced by the CPC Central Commission for Discipline Inspection and China Central Television, the series focuses on many senior corrupt officials' "depravation diaries" and tearful remorse for their wrongdoings. Their descriptions of how things went wrong in their political life, from bribery to embezzlement of public funds, highlight the need to press ahead with a new nationwide battle against corruption that started in 2012, and strengthen intra-Party supervision.

In the interviews they gave while in detention, some corrupt officials regretted believing they could get away with their misdeeds once they retired or were promoted to high positions. The fact that the corrupt officials, including Su Rong, former vice-chairman of China's top political advisory body, didn't manage to escape the law showcases the leadership's determination to end corruption and create a healthy political atmosphere within the Party.
