After the Western Han Dynasty, on Wednesday, the secretary was the first three officials in the East Palace, and he could also be appointed as a virtual post.
After the Tang Dynasty, three points on Wednesday were mostly in vain. The East Palace is the surname of Prince, Taifu and Taibao. Some people call it the three treasures (untested), which can be used to assist the prince or a false post;
After that, there are three titles in the East Palace, namely Prince Shao Shi, Fu Shao and Bao Shao, which are not permanent titles. The talents in the East Palace can be idle if they are not satisfied, or they can be used to seal posts and waste them in vain.
Therefore, Zhou Sansi, Sanbao Si and Sanshao Si are all officials of the East Palace (among them, Zhou Sansi is not the East Palace, but a young son of heaven), assisting the prince. If the prince is more respectful, he can be called the teacher of the prince.
As for the Qing Dynasty, Kangxi was taught by his grandmother, and the second brother Prince was taught by his father. Moreover, Master Kong's education for his second brother is that everyone is his slave ... After Yongzheng, it doesn't matter to be a teacher of the prince.
Although the prince of the Qing Dynasty studied hard, he showed the least respect for his teachers. The slave education in the Qing Dynasty made all ministers who taught the prince give him gifts, and sometimes they had to kneel down (for example, being a teacher for the second brother ... what a pity ...)
