The head of ZTE's four generals should be Yue Fei. Liu Guangshi has 50,000 old, weak and beaten soldiers, and basically has never fought a war. He became the four generals of ZTE only because he was a general with many soldiers and high ranks in the Song Dynasty. Wu Jun didn't have a job because he didn't have a high level and many soldiers, and he didn't have a good relationship with many senior officials at that time.
