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.
Duke Xi of Qi
Duke Xi reigned for 33 years and died in 698 BC. He was succeeded by his son, Duke Xiang of Qi, who would later be murdered by Duke Xi's nephew Wuzhi. Wuzhi himself was also killed soon afterward, and Duke Xi's younger son Xiaobai ascended the throne, posthumously known as Duke Huan of Qi. Qi grew strong under Duke Huan's rule and he became the first of the Five Hegemons of the Spring and Autumn period.
