Why the general who defend Great Wall of China was taken off the case-Annieli tours

Annieli tours’s Beijing Tour Guide answer:
The man called Yang Siwei burned with an ambition and always wanted to kill Qi Jiguang who was guarding Great Wall of China. But he had no opportunity to kill him because the prime minister of Ming Dynasty had a very high opinion of Qi Jiguang. Moreover, Qi Jiguang who had been protecting Great Wall of China came through countless fights and very clever, so it is very hard to kill him. After several years,the prime minister was dead. The fellow thought that the time is right to usurp the Qi Jiguang’s authority. He bought off eunuches and high officers, moving from place to place. Because the emperor was mediocre and incompetent, Qi Jiguang had been taken off the case.
