Is the story of Yang Jiajiang true?

Yang Jiajiang had it in the Song Dynasty. But the plots of Yang Jiajiang's stories are mostly fictional. It's just the history of the river, but the plot of the water margin is mostly fictional. Yang Jiajiang is a generation older than Yang Zongbao. Yang is the son of Yang in history. I became a grandson in the novel. Yang in history is actually the prototype in the novel. Mu Guiying is a fiction. But it is said that it has a certain embryonic form. This is Yang's wife. Formerly known as Murong. Mr. Murong and Mr. Mu are a little homophonic. At first, the name Yang Zongbao was regarded as fiction. Later, I found a man. But that's Yang's own woman.

Yang is not. He is the real Yang Dalang. Nicknamed Yang Liulang. Is to compare him to a six-star star. Yang Liulang was mistaken for the sixth.
