"Don't let pillow talk lead you down to corruption. Don't let your children engage in self-dealing using your name. Don't be dragged into the 'muddy water' by people around you," Xi warned.

He said officials should strengthen self control, not to be tempted by even the slightest profit and not to be confused among all sorts of seduction.

"Officials should never indulge themselves, never cross the line, never break the rule, and improve immunity to corruption," he said.

Other Chinese leaders Li Keqiang, Li Zhanshu and Zhao Leji also joined panel discussions with NPC deputies.

Speaking to deputies from Ningxia Hui Autonomous Region, Li Keqiang called for implementation of the country's "go west" strategy to make the region an inland pioneer in reform and opening up. He also asked the region to improve business environment by consistently deepening reforms, improve living standards, and resolutely secure a victory in poverty alleviation.

Meeting with deputies from Yunnan Province, Li Zhanshu said he hopes the province will build itself an exemplary region in promoting ethnic unity and progress, ecological development, as well as a center of opening up towards South Asia and Southeast Asia.

Joining deputies from Tibet Autonomous Region, Zhao Leji said the campaign against the mentality and action of privilege seeking should be continued. He called for actions against formalities for formalities' sake, bureaucratism and various kinds of misconduct, so as to keep the pressure on conduct problems.
