In Min's last years, he rebelled against its last emperor Wang Yanzheng and seized control of the Fu Prefecture (福州, in modern Fuzhou, Fujian) region, initially in nominal allegiance to both Southern Tang and Later Jin.
He was said to be "of Guang Prefecture" (光州, in modern Xinyang, Henan)[1]—but that probably did not denote that he was born there, but rather that his ancestors were from there, as the original Guang Prefectures immigrants to the Fujian region were led by Wang Chao, the brother of Min's founder Wang Shenzhi (Prince Zhongyi), in deciding to remain, in 885—six decades before Li Renda's coming of power.
[2] Li Renda himself at some point became an officer—the commander of the Yuancong Corps (元從)—for Min, but after reaching that position, did not receive another promotion for 15 years.
Zhu, disliking Li for his treacherousness, refused to give him any commissions and forced him into retirement at Fuqing (福清, in modern Fuzhou).
[1] In late 944, Zhu had in turn been assassinated by the officer Lin Renhan (林仁翰), who then submitted Fu to Wang Yanzheng's control.
[1] When Wang Yanzheng heard this, he slaughtered Huang Renfeng's family and sent the general Zhang Hanzhen (張漢真) to rendezvous with troops from Zhang (漳州, in modern Zhangzhou, Fujian) and Quan (泉州, in modern Quanzhou, Fujian), which had recently submitted to him, to attack the new Zhuo regime.
However, one day, Huang lamented to Chen his regrets in rebelling against Wang Yanzheng, stating:[1] For a person to be human, he is to be faithful, honorable, kind, and righteous.
He started using Southern Tang's Baoda era name, yet at the same time also sent emissaries to pledge allegiance to Later Jin and to establish friendly relations with Wuyue.
[1] In fall 945, Jian Prefecture fell to the sieging Southern Tang troops commanded by the general Cha Wenhui (查文徽).
[4] Previously, when Cha captured Jian, there were suggestions made to the Southern Tang court that the army advance and take over Fu as well.
The false edict also named Chen the acting overseer at Fu and launched troops from Ting (汀州, in modern Longyan, Fujian), Jian (the former Min capital), Fǔ (撫州, in modern Fuzhou, Jiangxi, note different location), and Xin (信州, in modern Shangrao, Jiangxi) Prefectures, under the command of the Jian army monitor Feng Yanlu, to head toward Fu to pressure Li Hongyi.
Later Jin's emperor Shi Chonggui commissioned him the military governor of Weiwu and the overseer of the state of Min.
Qian Hongzong bestowed on him the greater honorary chancellor title Shizhong (侍中) and gave him a new name of Li Ruyun.
Li Ruyun soon became apprehensive that Qian Hongzong might keep him at Qiantang, and, using 20 gold bamboo shoots, bribed the powerful general Hu Jinsi, requesting to be allowed to return to Fu.
[7] Bao delivered Li Ruyun's head to Qiantang, and Qian Hongzong subsequently sent the chancellor Wu Cheng to take over as the military governor of Weiwu.
