In 1973 he formed a poets' association, Tianlang Shihshe, and at the end of that year he came to Taiwan to continue studying. In order to raise money for poets' association he started writing wusia novels such as Sihda Mingbu Hui Jingshih. He had another poets association, Shenjhou Shihshe, from 1976 to 1980, but at the end of 1980 he and Fang Erjhen were deported from Taiwan the by the Taiwanese government for some political reasons.

He established a new style of writing. His novel, Shaleni Haoma, was published in Taiwan in 1987 and some of his earlier works such as Sihda Mingbu Hui Jingshih were published in Mainland China. From 1988 to 1989, he published a knight-errant story weekly Wun Ruian Wusia. And then he moved to China to promote his works for the past decade.

      When he wrote his earlier works such as Sihda Mingbu Hui Jingshih, Shienjhou Cisia and Cyuehe Che, he was influenced by the important books of Gu Long.
