Zhu Xi
In 1179, after not serving in an official capacity since 1156, Zhu Xi was appointed Prefect of Nankang Military District (南康軍), where he revived White Deer Grotto Academy. and got demoted three years later for attacking the incompetency and corruption of some influential officials. There were several instances of receiving an appointment and subsequently being demoted. Upon dismissal from his last appointment, he was accused of numerous crimes and a petition was made for his execution. Much of this opposition was headed by Han Tuozhou, the Prime Minister, who was a political rival of Zhu's. Even though his teachings had been severely attacked by establishment figures, almost a thousand brave people attended his funeral. After the death of Han Tuozhou, Zhu's successor Zhen Dexiu, together with Wei Liaoweng, made Zhu's branch of Neo-Confucianism the dominant philosophy at the Song Court.
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.
