BEIJING, June 12 -- President Xi Jinping has urged members of the Communist Party of China (CPC) to learn from veterans of the revolution, who are models of Party unity, discipline and morals.

Xi made the remarks Friday at a symposium to mark the 110th anniversary of the birth of Chen Yun, one such revolutionary.

"The bitter and glorious historical period of the 20th century saw the emergence of a huge number of outstanding CPC members. Comrade Chen Yun's firm belief, strong Party principles, earnest, frugal style and hardworking spirit deserve to be remembered forever," Xi said.

At the meeting, Xi recalled Chen's outstanding contributions to the revolution, and China's subsequent construction and reform, hailing him a "great proletarian revolutionary, politician, an outstanding Marxist, the founder of China's socialist economy and a tested, excellent Party and state leader."

Other leaders, including Li Keqiang, Yu Zhengsheng, Wang Qishan and Zhang Gaoli, also attended the meeting, which was presided over by Liu Yunshan.
