China's discipline watchdog is inviting Internet users to help ferret out officials' inconspicuous acts of corruption, in a new wave of the country's anti-graft campaign.

　　Accepting split-up gift money, driving private cars with expenses covered by taxpayers, feasting in secret clubs and villas -- these are among the clues the Central Discipline and Inspection Commission (CCDI) of the Communist Party of China solicits from the public on officials' invisible corruptions, according to a statement on the CCDI official website.

　　It is hard to root out misconducts of officials, though a high-handed anti-corruption campaign has brought many officials under investigation.

　　As a result, we need to guard against the resurgence of corruption in subtle forms and ensure consistency in fighting corruption, especially during holidays and festivals, said the statement.

　　Last Friday, CCDI also issued a statement which called for tight disciplinary inspection in the upcoming May Day holiday.
