Zhu Yuanzhang attached great importance to his family. Although he is uncomfortable with ministers, he is very comfortable with his sons. As the eldest son, Zhu Biao was naturally expected. Zhu Biao was born when Zhu Yuanzhang was attacking Nanjing. The birth of the eldest son gave Zhu Yuanzhang and his army great spiritual support. After all, the ancients attached great importance to children's problems. Zhu Yuanzhang has a son, which means that his career has been passed on.
As we all know, according to China's traditional patriarchal concept, the establishment of a prince should be "the establishment of an official position, not the growth of the establishment". The eldest son is the child born to his wife, the queen, and the eldest son is the first child. According to official records, Ma Huanghou actually has no children. Therefore, none of Zhu Yuanzhang's children was his own son, so he had to have his eldest son, so Zhu Biao stood out. Zhu Yuanzhang's love for Zhu Biao is deeply rooted in the bone marrow; As the heir to the throne, Zhu Yuanzhang was not very satisfied with Zhu Biao.
Zhu Yuanzhang insisted on the eldest son inheritance system, and the throne should be handed over to the eldest son, and this provision was listed as the ancestral system. Future generations must abide by it. Since Zhu Biao will inherit the throne in the future, Zhu Yuanzhang must be serious and teach Zhu Biao how to be an emperor in the future, so that he can always be together and have a long-lasting relationship. However, Zhu Yuanzhang has made it clear that the Ming dynasty throne was inherited by the eldest son. After Zhu Yuanzhang's death, the throne belonged to Zhu Biao. This is fundamental, and this cannot be shaken at all.
