 Li Huaiguang was vehemently against seeking Tibetan aid, however, citing how Tibetan troops would surely pillage the region and also seek excessive rewards, and he refused to cosign the aid request, and Shang refused to launch aid troops.Emperor Dezong's trusted advisor Lu Zhi, believing Li Huaiguang to be on the verge of rebellion and fearing that Li Huaiguang would take over the troops under Li Sheng, Li Jianhui, and Yang, urged that those three armies be separated from Li Huaiguang's army and take up position elsewhere; Emperor Dezong repositioned Li Sheng, but believing that relocating Li Jianhui and Yang as well would bring further resentment from Li Huaiguang, did not move them.Li Huaiguang, indeed, was then in secret communication with Zhu Ci and considering rebellion.
