Why did Guo Jing accept Yang Guo as his adopted son?

The two families are friends of the opposite sex (their father makes the decision). Guo Jing is Yang Kang’s adopted brother. Yang Guo’s name is Guo Jing, Uncle Guo, Huang Rong, and Aunt Guo.

In The Condor Shooting, Yang Kang harmed Guo Jing and Huang Rong many times. In the end, Duoxing unjustly tried to plot against Huang Rong, but was poisoned by Huang Rong's soft hedgehog armor (the poison was the residual poison that Yang Kang had poisoned Master Guo Jing in the past, and it gradually got on Huang Rong's armor and killed him). Later, Guo Jing and Huang Rong met Yang Kanggangsheng The child (Mu Nianci) and helped him escape. Mu Nianci asked Guo Jing to name the child Guo Jing went to Yang Guo, hoping that he would correct his mistakes and stop thinking about his father

Yang Guo, whose mother died in The Condor, met Guo Jing The couple Guo Jing felt sorry for him and wanted to take him home to adopt him because of the bond between the two families. Huang Rong had always hated Yang Guo's father's evil deeds. Seeing Yang Guo's strange spirit, he was afraid that Yang Guo would grow up to be like his father (and even though his father was not killed by himself) However, he also died because of him), so he was always on guard against being lukewarm to him and did not practice martial arts. Later, he was worried that Yang Guo's concern for Guo Xiang was retaliation for Guo Fu's harmless treatment of Xiao Longnu and Yang Guo. It was not until the battle of Xiangyang that he truly had no grudges (middle Although he also cares about Yang Guo, there are always misunderstandings between his daughter and the past)

When Yang Guo left Peach Blossom Island as a boy, he did not like this aunt. Later, when he grew up, he admired her very much when he dated Huang Rong. He was also somewhat grateful

But the cause of his father's death, her eldest daughter Guo Fu's recklessness, and Huang Rong's wariness made him not close to this aunt
