BEIJING - More efforts are needed to rectify officials' work styles amid the ongoing "mass-line" campaign, a senior Communist Party of China (CPC) official said on Sunday.

Liu Yunshan, a Standing Committee member of the Political Bureau of the CPC Central Committee, made the remarks at a campaign group meeting, telling officials to push forward with the campaign.

The first round of the campaign is coming to an end and second part will be carried out soon.

The one-year campaign was launched in June by China's leaders to boost ties between CPC officials and members and the people, while cleaning up undesirable work styles such as formalism, bureaucracy, hedonism and extravagance.

Liu called for officials to learn from experiences, listen to opinions from the public and conduct in-depth research to better carry out second-round work.

Liu asked leading officials and organs to take the lead in correcting undesirable work styles found in the first stage of the campaign.

The campaign has various stages, including special sessions for officials to launch criticisms of colleagues and themselves, rectification of problems, and inspection teams to supervise results.

Liu also demanded strict implementation of the "eight-point" anti-bureaucracy and formalism rule that was introduced at a meeting of the Political Bureau of the CPC Central Committee in late 2012, during the Chinese Lunar New Year holiday which begins on January 31.

He urged officials to expose violations of the "eight-point" rule in a timely manner.
