Encouraging and fully developing private school teaching in Yuan Dynasty not only promoted general education, but also supplemented the deficiency of school education. But also contribute to the development of professional academic research. According to Yuan Shikai, Lei Ying was born at the age of seven, but he had no money. His mother, Hou Shi, went north to Hunyuan, took risks and got ready. She studies to be a teacher. I am determined to learn, and my mother is also very filial. (Yuan) When Emperor Taizong was in power, the imperial court set up an elective examination. When the Confucian scholar returned home, he was weak and had to choose, so he called it the article. " Xu Qian was born a few years old and lonely, but he can still talk. His mother, Tao, dictated the Classic of Filial Piety and The Analects of Confucius, which I never forget. " A little longer, I am willing to learn, and I will learn from myself ... The orphans of "Sun Zhe" know how to set up their own warnings under the guidance of Cai's mother. After a long time, I am proficient in learning and my mother is very filial. Zhou inherited the "family study" and later became a famous Confucian teacher. Liu Bingshu studied hard, but he was young. Influenced by the Book of Changes, he understands Neo-Confucianism. Yan Fu "studied at the age of seven and was brilliant. He entered Dongping School with a weak crown and was named Rukangye". Wang Sicheng "was taught the Book of Filial Piety and The Analects of Confucius at the age of seven, and then he was able to recite them", "He made great progress after visiting Hanyang Caoyuan". There are many similar situations in biographies of historical figures, which mainly reflect the widespread phenomenon of taking home study and self-study as teachers.
