The contradiction of Libang in Li Lianghui

Hello, it is said that it was because of falling out with Li Bangkui, the political commissar of the army, which seriously affected the development and construction of the army. In addition, the promotion speed is too fast and the foundation is shallow, so I transferred to the National Defense University to study. According to the military records of Ningxia, Li Lianghui went to shenyang military area command Air Force to assist in the work in February 1987, and was awarded the rank of senior colonel in June 1989. There seems to be no real work arrangement at this time. Until June, 1990, he was appointed as the deputy commander of Ningxia Military Region (retaining the treatment at the rank of army commander).
