Zhu Xi (1130 - 1200), also known as Zhuzi, was a major Song dynasty philosopher and commentator, but at the time his ideas led to his being dismissed several times from official positions. He was born in what is today Youxi County in Fujian province, where his father was serving as an official, but his home town is considered to be Wu Yuan, now in the northeast corner of Jiangxi province, but then part of Huizhou, a district just south of Huangshan. He spent many years teaching in the Wuyi Mountains on the modern Fujian/Jiangxi province border, and is also particularly associated with two Confucian academies, the Yuelu Academy in Changsha and one at his retreat by the White Deer Grotto in Lushan, northwest of Poyang Lake.
