History is really interesting to say. It was only when Li Shimin launched the palace coup (called "Xuanwumen Change" in history) that he seized power and reached the pinnacle of power. However, he did not expect that in the later years, such things happened to him. His eldest son, Li Chengqian, tried his best to emulate Li Shimin's feat, and came to a "change of Xuanwumen" and killed his brother Li Thai, forcing Li Shimin to make way!
Of course, don't worry about the final outcome. How could Li Chengqian have played with his father? He was finally caught by Li Shimin. However, Li Shimin really loved this son so much that even in the end, even Li Chengqian rebelled, Li Shimin was reluctant to kill him, but he was finally imprisoned until he finally became old!
So what is the main reason for this tragedy? We'll see it a little bit. Li Chengqian is the eldest son of Li Shimin and the eldest grandson, and the eldest son of Miao Hong who is rooted in Miao Hong. We all understand the great love between Li Shimin and the eldest grandson, and they are absolutely true love. Therefore, Li Chengqian's status is almost unshakable.
Things really did, as we thought, Li Shimin's love for his eldest son was in his bones. Li Shimin just became emperor and made this clever son a prince. At this time Li Chengqian was only eight years old.
