When a public official is reported for fraud, the source of the public official’s funds will be investigated.

According to the "Anti-Money Laundering Law of the People's Republic of China", banks, insurance, securities, futures, funds, trusts, pawns, auctions, cultural relics management and other institutions should treat customers when conducting business. Conduct due diligence on the customer’s identity, occupation, source of funds, etc., and establish a file of customer identity and transaction records. If a public official is reported for fraud, the police can check the files of these institutions during the investigation to understand the source of the public official's funds, so as to ascertain the facts of the case and recover the defrauded funds.

Public officials, as staff of state agencies, have special duties and are subject to higher legal supervision and public attention.
