BEIJING, June 12 -- The leading group of the Communist Party of China (CPC) "mass line" campaign on Thursday ordered continued fight against undesirable work styles.

The campaign was launched in June 2013 to bridge gaps between CPC officials and members, and the public, while cleaning up undesirable work styles such as formalism, bureaucracy, hedonism and extravagance.

In a circular issued by the leading group, authorities are required to "punch heavily" and "take practical actions" to clean up unhealthy work styles, enforce strict work disciplines, cut red tape and punish officials who abuse their power for personal gains.

CPC officials and members are told to reject nepotism in poverty-relief programs and refrain from formalism in implementing the campaign.

The public are welcome to supervise the campaign via hotlines and surveys, and authorities should expose malpractice that infringes upon people's interests, according to the circular.
