Korean Confucianism
Under the succeeding Han Dynasty and Tang Dynasty, Confucian ideas gained even more widespread prominence. During the Song Dynasty, the scholar Zhu Xi (AD 1130–1200) added ideas from Taoism and Buddhism into Confucianism. In his life, Zhu Xi was largely ignored, but not long after his death his ideas became the new orthodox view of what Confucian texts actually meant. Modern historians view Zhu Xi as having created something rather different, and call his way of thinking Neo-Confucianism. Neo-Confucianism held sway in China, Japan, Korea and Vietnam until the 19th century.
Zuo Ci
Zuo Ci, courtesy name Yuanfang, was a legendary personage of the late Eastern Han dynasty and the Three Kingdoms period (169 – 280 AD) of China. Though he is known to be from Lujiang Commandery (盧江郡; around present-day Lu'an, Anhui), the years of his birth and death are unknown. It is believed that he had existed before the collapse of the Han dynasty, and it is claimed that he lived until the age of 300. He learned his magic and path to longevity from the Taoist sage Feng Heng (封衡), and eventually passed his arts to Ge Xuan.
