The seven members of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee have called on officials to vigorously promote the "mass line" education campaign and apply it to boosting development and people's livelihoods.

"Officials should set an example by studying and bearing in mind the 'mass line' guideline, always seeing things from the perspective of the masses," said a Tuesday statement.

"Mass line" refers to a guideline under which Party members are required to prioritize the people's interests and persist in representing them and working on their behalf.

The seven members have conducted or will conduct inspections as part of the campaign.

Chinese President Xi Jinping, Premier Li Keqiang, Zhang Dejiang, Yu Zhengsheng, Liu Yunshan, Wang Qishan and Zhang Gaoli have visited Hebei Province, the Guangxi Zhuang Autonomous Region, Jiangsu, Gansu, Zhejiang, Heilongjiang and Sichuan provinces.
