The difference between heroes and old people in Jin Yong's works

Heroes can be old people (such as Hong Qigong in The Legend of the Condor Heroes and The Legend of the Condor Heroes, and many young (young) heroes written by Jin Yong, such as Guo Jing and Xiao Feng, but personally, the old people who can be called heroes must belong to Hong Qigong).

But the old man is not necessarily a hero (the representative figure in Hua Tiegan's "Flower Old Hero" is Liancheng; Xie Yanke in Chivalrous Man; The treasure tree monk in Flying Fox of Snowy Mountain; Ouyang Feng, Qiu's brother and sister and extinction teacher in the trilogy of condor shooting; There are too many people like Elder Xu in "Eight Dragons", so I won't list them one by one.
