The heroic prototype of Dragon Valley is the same as the historical prototype of Li Yunlong in Bright Sword, that is, the founding lieutenant general Wang Jinshan. The difference is that "Long Dagu" is a war hero who was born in a big family and was forced to embark on the road of anti-Japanese war. He retains the basic literacy of a big family, loves reading art books and has basic cultural literacy. However, due to the war years, he was in a barracks. In order to lead the revolutionary team, he must be brave and fearless to be convincing. In A Hero, the combination of bookishness and "soldier bandit" temperament is undoubtedly a new interpretation of the hero of the Anti-Japanese War.

Wang Jinshan (19 15- 1978), formerly known as Wenshan Wang, was born in Xujiatian Village, Gao Qiao, Huang An (now Hong 'an) County, Hubei Province, and was from a poor peasant family. A famous senior general of China People's Liberation Army, 1955 awarded the rank of Lieutenant General, and won the first-class August 1st Medal, the first-class Medal of Independence and Freedom, and the first-class Medal of Liberation. General Wang Jinshan has a nickname "Crazy Wang", because in a battle, he had a fight with a Kuomintang soldier and got red in the eye. As a result, they both rolled off a cliff together. Kuomintang soldiers were killed on the spot, but Wang Jinshan survived, only being poked in the head by a cone stone. From then on, his comrades-in-arms called him "Wang Crazy"
