It is understandable that the descendants of Yue Fei do not marry enemies. Why don't benefactors get married?

The first important reason is that Yue Fei has doubts about the future of his offspring. In ancient times, the heirs of the eldest son played a very important role in both the royal family and ordinary people's homes. So because of this mechanism, the ability of the heir can not be guaranteed. Yue Fei was afraid that his descendants would affect the descendants of the benefactor, so he did not allow the two families to marry.

The second important reason is that Yue Fei was persecuted by traitors, so the descendants of Yue Fei are likely to be persecuted by traitors. Although Yue Fei said that he defended his country before his death, he offended many people before his death. These people have been staring at Yue Fei's family. Therefore, Yue Fei does not allow his descendants to marry the descendants of the benefactor, in order to protect their descendants and the descendants of the benefactor to live a better life.

The third important reason is that the quality of Yue Fei's descendants is not very good. Yue Fei saw before his death that his descendants did not always have the same noble qualities as himself, so for Yue Fei, who always attached importance to moral quality, he didn't like such descendants at all, let alone marry his children and benefactors.

Another important reason is that the Emperor of the Southern Song Dynasty repaid Yue Fei's contribution to defending the country. Therefore, most of the descendants of Yue Fei were appointed by the royal family, and the descendants of Yue Fei have been appointed by the emperor to marry. Therefore, the descendants of Yue Fei have no chance to marry the benefactor's children, which is not difficult to explain why Yue Fei won't let himself.

Based on the above reasons, we can easily find that there are many reasons why Yue Fei refused to let his descendants marry the descendants of the benefactor, including his own reasons and royal reasons, which led to no chance to marry the descendants of the benefactor.
