In fact, the topic of this question is somewhat off-topic, but there are still many particularly powerful children of emperors. For example, Yongzheng, the son of Kangxi, and Qianlong, the son of Yongzheng, are still good emperors, such as Li Shimin, the son of Tang Gaozu. These emperors have good family education.

However, there are indeed some emperors in history who have made outstanding achievements, but their sons are unproductive emperors, and some even single-handedly destroyed the family country. Why is this? Is it really because of the royal tutor? Of course not. I think there are several main reasons.

The first reason is that these emperors are usually too busy, and they are worried about state affairs as a whole. They are really busy. Therefore, of course, they neglected the education of princes. Even if they hire special teachers, it is difficult to guarantee that they will lose their rare qualities in extravagance and waste.

The second reason, I think, is that, after all, princes were born with golden spoons and spoiled from childhood. The flattery and doting of people around them may make them lose their direction early, so after they inherit the throne, they only know pleasure and no longer have the glory of their parents.

The third reason, I think, was instigated by the treacherous court official. Many young princes, because of their inexperience, are easily bewitched by treacherous court officials around them, making some wrong decisions, and over time they become puppet emperors manipulated by people. For example, Hu Hai in Qin Ershi is a typical example, isn't it?

In fact, in the feudal society of China, it was often the case that such a son was inferior to Lao Zi. For example, Emperor Yang Guang of Yang Di was much worse than his father, and Li Shimin, the son of Emperor Taizong, became henpecked ... There was absolutely no problem with the education of the royal family. The problem is nothing more than the above three points.
