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.
Zhu Jin
Zhu Jin (朱瑾) (867-918) was a warlord late in the Chinese dynasty Tang Dynasty who would later be a major general of the Wu (also known as Hongnong) state during the subsequent Five Dynasties and Ten Kingdoms period. In the late Tang years, Zhu Jin, as the military governor ("Jiedushi") of Taining Circuit (泰寧, headquartered in modern Jining, Shandong) would form a power bloc with his cousin Zhu Xuan the military governor of Tianping Circuit (天平, headquartered in modern Tai'an, Shandong), but they were both eventually defeated by Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan). Zhu Xuan was killed, and Zhu Jin fled to the domain of Yang Xingmi the military governor of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu); he would thereafter serve under Yang and Yang's successors, whose domain formed the Wu state eventually. In 918, angry at the arrogance of the Wu junior regent Xu Zhixun (the son of the regent Xu Wen), he assassinated Xu Zhixun, but Xu Wen's troops attacked him; he committed suicide when he saw that there was no escape.
