Tang Taizong valued talented people, and he happened to be a connoisseur of calligraphy and painting as well as a calligrapher at that time. Li Tai was the fourth son among all the sons of Emperor Taizong of the Tang Dynasty. According to historical records, his father doted on him more than all his children. He was the favorite of Emperor Taizong of the Tang Dynasty among all his sons. He was talented, extremely intelligent, loved literature, and had a collection of thousands of books. He was allowed to set up a literature museum in the palace, and was allowed to invite bachelors and organize cultural salons.
Li Tai was good at literature and martial arts, and his figure was fat, round and honest, so Emperor Taizong of the Tang Dynasty favored him. It is precisely because of his father's preference that Li Tai's life can be said to be dominated by wind and rain. Although his status is not as good as that of his brother Li Chengqian, he has overshadowed all his brothers. Tang Taizong even worried about his being too fat. Due to physical inconvenience and fatigue, he was given a sedan chair to go to court every day.
It is said that one time Li Tai said that the court ministers did not respect him, which made Emperor Taizong very angry immediately. He flew into a rage and rebuked many officials so severely that the ministers did not dare to speak. Although Tang Taizong later knew that it was his mistake, he still doted on the child as before. The ministers had no choice but to continue to suffer silently. After all, they were just ministers, taking orders and accepting appointments from the king.
However, Li Shimin's favor is only because Li Tai is chubby and talented. According to the traditional succession law of the Han family, Li Tai cannot sit in the position of crown prince, so no matter how much his father dotes on him, Li Tai can only be named crown prince. Although history had given Li Tai a chance, it was precisely because of his father's pampering that he was adversely affected. Li Shimin finally changed his name to the crown prince for the sake of peace between Li Tai's brothers.
