Zhang Sanfeng
Zhang Sanfeng () (also spelled Zhang San Feng, Chang San-Feng) refers to a legendary Chinese Taoist who many believe invented T'ai chi ch'üan. However, other sources point to early versions of Tai Chi predating Sanfeng. He was purported to have achieved immortality. According to various accounts, he was born in Shaowu, Nanping, Fujian near the end of the Southern Song dynasty (around 1270 C.E.) and lived for over 307 years until the mid-Ming dynasty. His given name was Tong (通) and his courtesy name was Junbao (). He specialised in Confucian and Taoist studies, scholarly and literary arts. During the reign of Emperor Shizu in the Yuan dynasty, he was nominated as a candidate to join the civil service and held office as the Magistrate of Boling County (博陵縣; around present-day Dingzhou, Baoding, Hebei). While touring around the mountainous regions near present-day Baoji, Shaanxi, he saw the summits of three mountains and decided to give himself the Taoist name "Sanfengzi" (三丰子), hence he also became known as "Zhang Sanfeng".
