During Jin Dynasty
When Xie Hui was young, he served on the staff of the official Meng Chang (孟昶). When Meng committed suicide in 410 over disagreements he had with Liu Yu over how to counter the attack that the warlord Lu Xun (盧循) was making on the capital Jiankang, Liu Yu asked his chief assistant Liu Muzhi (劉穆之) whom among Meng's staff he can retain. Liu Muzhi recommended Xie, and Liu Yu added Xie to his staff. He subsequently contributed to Liu Yu's campaign against Sima Xiuzhi (司馬休之) in 415, and therefore became increasingly important as a strategist for Liu Yu. However, because his opinion often differed from Liu Muzhi's, Liu Muzhi opposed promoting him, and Liu Yu did not promote him further until Liu Muzhi's death in 417. Despite this, the general Tan Daoji later remarked that of the 10 strategies that Liu Yu used to conquer Later Qin in 416 and 417, nine came from Xie.
