Why are the sons of many famous Three Kingdoms like garbage?

I think it has a lot to do with education! First, fathers know how to educate children, such as Liu Bei. According to records, Liu Chan was actually very clever when he was young, and even Zhuge Liang praised him. However, it is precisely because Liu Bei did not know how to educate children and let them develop themselves that Liu Chan became playful. He played with insects before the emperor and played with women after the emperor. Liu Chan had an unshirkable responsibility in the fall of Shu Han. Second, does the father have time to educate his children, such as Zhuge Liang and Zhao Yun. Zhuge Liang can be said to be the pillar of Shu Han. He pays attention to politics and military affairs, and the only time he has is spent on cultivating Jiang Wei. He has no time to get close to his son, and his son can't get an answer from him when he meets a problem. Even if his son is gifted again, he will inevitably disappear in the end without the correct training of his father. The sons of general famous soldiers all inherited their father's talents, such as Guan Ping and Guan Xing. Guan Xing's military strength is much higher than Guan Ping's. Why? Because Guan Xing is Guan Yu's own and inherits his father's genes, his physical quality is naturally better than ordinary people. After his father's guidance and training, Guan Xing's force can easily reach the level of first-class military commanders. Guan Ping is only Guan Yu's adopted son, and his physical quality is not strong enough. Even if he often fought with Guan Yu, he was often commanded by Guan Yu, and Guan Ping's strength was only the level of a second-rate military commander.
