A famous anti-Japanese warrior and a faithful believer of the Three People's Principles. Typical positive image of Kuomintang officers. Those who are loyal to Fu have contradictions with Chiang Kai-shek. Anti-communism, the main battle, but extremely national integrity. As a master of guarding the city, he has been through many battles and has something that others can't match. As the saying goes, "Taishan collapses in front, and the color remains the same." He is resourceful, versatile and personable, with the demeanor of a middle-aged man and general unique to traditional soldiers in China. It is believed that the generals died in battle, and only the beheaded generals did not surrender.

Li Changyu is the central figure in this play. His upright and unyielding attitude makes people respect and admire him. He put the interests of the Kuomintang first, followed Fu as his lifelong belief, and held a tenacious attitude towards Enemy at the Gates. He attaches great importance to feelings and righteousness, and takes the daughter of his comrades (Liu Yuyu) as his own. He is the only person in the PLA who has scruples. He fights corruption and advocates honesty. He is an alternate officer of the Kuomintang ... he knows management and team building, and he has the foresight and foresight that others did not have at that time.
