Louis Cha Jing-yon (10 March 1924 – 30 October 2018), better known by his pen name Jin Yong, was a Chinese wuxia ("martial arts and chivalry") novelist and essayist who co-founded the Hong Kong daily newspaper Ming Pao in 1959 and served as its first editor-in-chief. He was Hong Kong's most famous writer.
His wuxia novels have a widespread following in Chinese communities worldwide. His 15 works written between 1955 and 1972 earned him a reputation as one of the greatest and most popular wuxia writers ever. By the time of his death he was the best-selling Chinese author, and over 100 million copies of his works have been sold worldwide (not including an unknown number of pirated copies).
