Zheng Rang's trip to Liangzhou was not of his own accord, nor did he support Prince Chu. After taking office in the capital, Zheng Rang, like Prime Minister He and others, was loyal only to the Emperor, not to any prince.
Two years ago, the Emperor suddenly decreed that Zheng Rang should go to Liangzhou to assist Prince Chu.
Regarding this decree from the Emperor, Zheng Rang naturally could not defy it, and had to dutifully go to Liangzhou. Before leaving for Liangzhou, the Emperor had summoned him and repeatedly urged him to assist Prince Chu well.
Zheng Rang couldn't quite grasp the Emperor's intentions at first. Before departing, he specifically consulted Prime Minister He and Grandmaster Liu, asking if the Emperor wanted him to serve Prince Chu.
Prime Minister He and Grandmaster Liu told him that he should do whatever the Emperor instructed. Since the Emperor wanted him to assist Prince Chu, he should do so with dedication and loyalty.
