In Hu Jun's version of Dragon, Duan's woman was killed. Does Duan Yanqing know that Duan Yu is his own son after seeing Duan Yu's birthday book?

First of all, Duan Yanqing didn't know that Duan Yu was his son until he saw Duan Yu's eight characters, because as soon as he saw Dao Baifeng, he knew that she was Guanyin outside Tianlong Temple.

Look at Duan Yu's horoscope again, and you will know that Duan Yu is not Duan's son, but his, so he will save Duan Yu at a critical moment.

Then, trying to kill Mrs. Wang should actually be said to be induced by Duan. Duan watched the woman he liked die indirectly in the hands of Wang Fu, and decided to avenge them, so that it doesn't matter if he killed those women in front of him.

Mrs. Wang is the only person he cares about most; In order to force Duan to give way, when Duan said this, he naturally threatened to kill Mrs. Wang.

Finally, Duan changed his mind and asked to kill Mrs. Wang because Duan saw Mrs. Wang's sad appearance and remembered their previous events, so he forgave Mrs. Wang in his heart and changed his mind and asked to kill Mrs. Wang. His purpose is to make Mu Rongfu suspicious and let Mrs. Wang go.
