BEIJING, Nov. 20 (Xinhua) -- Li Ao, born in 1935 and Taiwan's controversial writer and critical non-partisan legislator, announced that he would not participate in the next legislative election, according to reports by Taiwan-based media.

Li made the announcement at a ceremony for the publishing of his new book "Li Ao's Sorrows on the Legislative Forum" on Tuesday, the deadline for the registration of candidates who want to join in the seventh election of Taiwan's "legislative Yuan" (the island's "parliament").

Li, who is a supporter of one-China policy, said he would save the 200,000 Taiwan dollars of registration fee to spend on his son's middle-school education.

After he quits politics, Li said, he would return to his original career as a writer. Li plans to write two books a year in the future.

Li said his new book is composed of his speeches during his three-year legislative term.

In September, Li established the China Wisdom Party and announced his plan to participate in the next legislative election.

There is no report on why Li changed his mind.

Li, who was born in Harbin and fled from Shanghai to China’s Taiwan in 1949 with his family, is widely known for his open and critical words against both Taiwan's ruling Democratic Progressive Party and the main opposition party Chinese Kuomintang (KMT).

In 1971 he was imprisoned by the KMT because of his pro-democracy stance. He was freed in 1976, but many of his 100-plus books have been banned at different times by the island authorities.
