중국 철학자 정이 생일은 언젠가요?
Cheng was born in Luoyang, Henan in 1033. Cheng entered the national university in 1056, and received the "presented scholar" degree in 1059. He lived and taught in Luoyang, and declined numerous appointments to high offices. He campaigned against the reformist policies of Wang Anshi, and after the reformers were dismissed from office, he was appointed expositor-in-waiting in 1086 to gave lectures to the emperor on Confucianism. He was more aggressive and obstinate than his brother, and made several enemies, including Su Shi, the leader of the Sichuan group. In 1097, his enemies were able to ban his teachings, confiscate his properties, and banish him. He was pardoned three years later, but was blacklisted and again his work was banned in 1103. He was finally pardoned in 1106, one year before his death.
