In 907, Zhu Quanzhong had the
Tang dynasty's last emperor,
Emperor Ai, yield the throne to him, ending Tang and starting a new Later Liang as its Emperor Taizu. He created his sons imperial princes, and Zhu Youwen, who had become the deputy military governor of Xuanwu before he took the throne, was given the title of Prince of Bo. Emperor Taizu also made Zhu Youwen the mayor of
Kaifeng (i.e., the old Xuanwu headquarters), as well as the director of Jianchang Hall ()—a conversion of the office overseeing financial matters for the four circuits into an imperial institution. After Emperor Taizu formally made
Luoyang his capital in 903, he also made Kaifeng the eastern capital and Zhu Youwen its defender. It was said that, after this point, Zhu Youwen often spent time in drinking and was not as attentive to his responsibilities as before. In 911, after Emperor Taizu summoned Zhang Shensi () the prefect of Cai Prefecture (蔡州, in modern
Zhumadian,
Henan) to Luoyang, the Cai Prefecture officer Liu Xingcong () mutinied and prepared to lead the soldiers to flee to Later Liang's rival
Hongnong. Another officer, Wang Cunyan (), killed Zhang and claimed the title of prefect. Zhu Youwen, displeased that Wang was claiming such authority without first receiving imperial commission, sent an army to attack Wang, but when Emperor Taizu heard this, he pointed out that doing so would force Wang into fleeing to Hongnong, and therefore sent messengers to stop Zhu Youwen from attacking Wang. (Emperor Taizu later made Wang the prefect of Cai.) After a failed campaign against rival
Jin in spring 912, Emperor Taizu fell ill and spent summer 912 at Wei Prefecture (魏州, in modern
Handan,
Hebei) to recuperate. While he was recuperating, Zhu Youwen went to Wei Prefecture to see him and suggested that he visit Daliang (i.e., Kaifeng). Emperor Taizu accepted the suggestion, and visited Daliang before returning to Luoyang. == Death ==
