In ancient China, the succession to the throne usually followed the system of the eldest son inheriting the throne. Di son referred to the son born by his wife, while the eldest son referred to the oldest son. There were many reasons behind the system of eldest son succession, including maintaining the stability of the imperial power and avoiding internal disputes, ensuring the smooth and orderly succession of the throne, and meeting the requirements of Confucian ethics. However, in reality, the system of succession of the eldest son might be affected by the emperor's personal preferences, the interference of the powerful and influential forces, and other factors. Therefore, if the eldest son died, the heir to the throne might be the eldest grandson or other suitable heir.

The status of a legitimate son was higher than that of the eldest son. A legitimate son was a son born to his wife, while the eldest son was the eldest son in the family, regardless of who his biological mother was. In ancient China, the Di Shu system was strict, and the Di son had priority in inheritance, even if he was not the eldest son. The status of a legitimate son was higher because he had the priority to inherit the family property. The eldest son was the first son born to his wife. He had the highest status among all the children. The eldest son of a concubine was the eldest son of a concubine or a concubine, and his status was relatively low. Generally speaking, Di sons had a higher status than Shu sons, and the eldest son had the highest status.
The difference between a legitimate son and an eldest son was their status and inheritance rights. The eldest son was the first son among all the sons born to the male master and his wife, while the legitimate son was all the sons born to the male master and his wife. The eldest son was the first son of the male master and his wife. The eldest son had the first right of inheritance among all the sons, followed by a bunch of legitimate sons, and finally, it was the turn of the illegitimate sons. The right of inheritance of the eldest son was unchangeable. Even if the male master remarried or had another child, the eldest son would still maintain the first right of inheritance. The status and inheritance rights of the eldest son and legitimate son were determined according to the specific situation.
Under the traditional etiquette system, a legitimate son was usually the son of the legitimate wife. If the empress was the emperor's wife, then the eldest son of the empress was usually considered a legitimate son. In many novels related to historical backgrounds, the identity of a legitimate son was often associated with important plots such as the succession of the throne. For example, the eldest son inheritance system stipulated that the eldest son had priority in inheriting the family business, the throne, and other rights. However, the plot settings of different novels might be different. Some novels might have unique creative settings for the definition of a legitimate son or the status and experience of a legitimate son in the story. For example, there might be plots such as the identity of a legitimate son being deprived or the betrayal of a concubine. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
