When I was a child, Yin Yong lived with Emperor Kangxi, who was also the first teacher of the prince. Kangxi is a very learned man, and he has high hopes for his future successor. To this end, he personally formulated a comprehensive and thorough policy and steps. Compared with other emperors, Kangxi paid special attention to the growth of the prince and devoted a lot of effort to his education. He has publicly stated that he has two important things a day, one is to greet the Queen Mother, and the other is to ask about the academic situation of the Crown Prince. Before Yin Yong was six years old, his father taught him to study. When the prince was six years old, he became a fu. The emperor chose famous Confucian scholars Zhang Ying, Li Guangdi and Xiong Cilv as his teachers. A little longer, he specifically asked Tang Bin, a famous Neo-Confucianism scholar, to be Zhan Shifu. Yin Geng's reading room was first in Yuqing Palace, the imperial city; Later, Kangxi determined that the study room of the Crown Prince was Wuyi Zhai in Changchun Garden (its tutors included Tang Bin, Xu Chao, Gao Zi, Xiong Cizan, Geng Jie, Dahata, Yin Tai, etc.). ): Kangxi's education for the prince is very strict. The prince never stops learning and asking questions regardless of the cold and heat. Because the prince is talented, he can recite all the books he has read several times, but he still has to recite each article 120 times according to his father's request-he reads "clear rhyme, sonorous sentences, repeated intonation and endless irony", so his study has made rapid progress. Kangxi once said, "The Crown Prince never knew anything but reading and playing." So the crown prince can skillfully use Manchu and Mongolian to master martial arts. "Riding and shooting, writing and literature are everywhere."
