A senior official of the Communist Party of China (CPC) has called for a new campaign designed to boost CPC-people ties to be carried out properly in order to bring a "big improvement" of officials' work styles.

Liu Yunshan, head of a leading group formed by the CPC Central Committee to direct the campaign, made the remarks at a meeting held on Tuesday, the same day the year-long campaign was officially launched, according to an official statement issued on Wednesday.

Bad work styles involving formalism, bureaucracy, hedonism and extravagance take different forms in different departments and localities, Liu said.

"Each department or organization should act according to its own actual situation and strive to spot problems, analyze their causes and find specific solutions," he said.

Whenever a problem can be solved earlier, it should be, so as to bring "a big improvement in officials' work styles," according to Liu, who is also a member of the Standing Committee of the Political Bureau of the CPC Central Committee.

Liu urged local authorities to learn from a speech given by President Xi Jinping during a Tuesday meeting that marked the start of the campaign.

Xi described the campaign as a "thorough cleanup" of undesirable work styles.

Talking about why the improper practices concerning officials' work styles occurred, Liu said the origin of the problem is that some Party officials are going against the nature of the CPC in their ideological fronts.

The priority for the campaign is to mobilize Party officials to grasp the essence of the 18th CPC national congress last year and arm themselves with socialist theories with Chinese characteristics, he said.

He continued that education efforts should focus on promoting serving-the-people and down-to-earth work styles as well as cleanness and honesty among Party members and officials.
