BEIJING, March 24 -- Local Communist Party of China (CPC) organizations and officials at all levels across China are urged to study President Xi Jinping's recent remarks on the "mass-line" campaign.

The speech and requirements of Xi should be studied carefully, understood and carried out, said a circular issued by the leading group of the CPC's mass-line campaign and published on Monday.

During his visit to central China's Henan Province last week, Xi suggested a more stern and sharp approach in the anti-decadence campaign.

Xi also recalled the spirit of Jiao Yulu, a model official who worked in the province's Lankao county in the 1960s and devoted his life to combating sandstorms, saline-alkali land disasters and floods and improving people's livelihoods.

Every Party organization and Party member should set a high, strict standard in implementing Xi's requirements and cleaning up the four undesirable work styles -- formalism, bureaucracy, hedonism and extravagance, the circular said.

The circular urged CPC members and cadres to take Jiao as an example and improve their ideological integrity, personal qualities and their images among the public.

It called on officials to maintain a healthy work and life style and keep vigilant against corruption.
