At first, Liu Jun took a fancy to this woman at a palace banquet, and then he tried his best to get her and named her Yin. From then on, there were no other concubines in the harem in his eyes, and he was with her all day. Soon after, Yin gave birth to a son and named him. With the birth of her son, her status as a biological mother is much higher.
Because Yin is his favorite woman, he is naturally his favorite son, and he is very smart since he was a child, just like a child prodigy. I was able to read four books and five classics when I was very young. At that time, Liu Jun was very concerned about the child. Since then, unfortunately died. From then on, Liu Jun liked Ziyuan Liu even more because he missed his wife. After all, this child is the only crystallization and bond between them.
However, emperors of all ages made their eldest son a prince, so they couldn't break the routine, so they made Prince Wei Liu from the beginning. After owning Ziyuan Liu, he also wanted to abolish Liu's Prince Ye Zi and establish Ziyuan Liu, but ministers opposed it. After that, the first thing Liu did after he succeeded to the throne was to put him to death, because he was once the elected prince in his heart. And he also knows that Ziyuan Liu is a talented person. If we don't get rid of him, I'm afraid more things will happen in the future. To put it bluntly, he just thinks that Ziyuan Liu is a time bomb for him, so he must be ruled out first.
