The problems with work conducts of party members and state officials concentrate on the four kinds of misconducts. Since the 18th National Congress of the Communist Party of China （CPC），the Central Committee of CPC has put forward a series of institutions and regulations，built several long-term mechanisms for improving work conduct，strengthened the work of party discipline inspection and accountability，and created many methods to inspect and punish four kinds of misconducts. Through unceasingly effort in the past five years，the four kinds of misconducts has been declined. But，largely invisible problems of “Four Kinds of Misconducts” still take place from time to time. In order to solve these problems，thoughts and actions still need to be unified，upper-level officials still need to set examples for lower-level subordinates，institutional construction and implementation still needs to be improved，long-term mechanisms still need to be promoted，and public supervision and family ethics still need to be strengthened.
