Ma Xiaochun (Simplified: 马晓春; Traditional: 馬暁春; Hanyu Pinyin: Mǎ Xiǎochūn, b. August 26, 1964 in Zhejiang, China) is a Chinese professional 9-dan, author, and head coach of the Chinese National Team?. He is best known for his title victories throughout the 1990s, dominance of the Chinese Mingren title, first Chinese player to win an international title, and light, flexible play style.
Ma began playing go at the age of nine, and half a year later placed third at a local youth tournament. In 1982 (when he was 18), he was awarded an amateur 7-dan rank. In early 1983, he won the 5th World Amateur Go Championship and was promoted to professional 7-dan status. By the end of the year he had been promoted to 9-dan status through a series of rank promotion tournaments. He became a full-time professional in 1985. During 1985-88 he won several titles, including the Tianyuan, National Go Individual and New Sports Cup.
Beginning in 1989 he won the 2nd Mingren title and held it for thirteen consecutive years until 2002. Throughout the rest of the 1990s he earned over 25 other titles, having his best year in 1995. During this year he became the first Chinese player to win an international title -- the Tong Yang Securities Cup. From 1996-99 began an international rivalry with Yi Changho, battling each other several times for the Tong Yang Securities Cup, Fujitsu Cup, Samsung Cup and LG Cup. He also maintained a healthy rivalry with fellow countryman Nie Weiping. In 2005, Ma Xiaochun was officially nominated (and appointed) as 'head coach' of the Chinese National Team. 
Ma has been noted for his light, airy, elegant and dodging style and opening play. In his early years, this style would clash strongly with that of Liu Xiaoguang in several important tournament matches. Liu played a fierce, combative style opposite to Ma's. Further down the road, Ma's airy style of play would continue to give attacking players a difficult time.
