In the Song Dynasty, there were many names of Mongolian schools, such as rural schools, village schools, home schools, libraries, etc., as well as winter schools specially set up for poor children in the slack season. Most of this kind of ignorance is not as formal as official learning, and the teaching quality is also low. In Lu You's poem "Autumn in the Suburb" in the Southern Song Dynasty, the teaching situation of winter learning at that time was recorded: "Children learn winter better than their neighbors, but according to the case, fools cherish themselves, teach them to sleep behind closed doors and never look at people all the year round." Lu you's note: farmers send their children to school in October, which is called winter school; What you read, such as Zazi and Hundred Family Names, is called a village book. Judging from this "stupid scholar" who usually sleeps behind closed doors, regardless of the children's frolicking, he still talks about village books seriously. His education quality is low, but the relationship between teachers and students is rather casual. Farmers send their children to learn to read village books in winter leisure season. The purpose is just to learn a little superficial cultural knowledge. The requirements are not high, the settings are seasonal, the conditions are simple, and the income of teachers is naturally low. In the Southern Song Dynasty, Ye Mengde's "Shilin Speech" was traced back to a man named Le Jun, his first childhood teacher. His family is very poor and has three small houses. Two of them are raw, and one is for his wife. He lectures for a living. Usually, because of laziness, he often goes hungry and suffers from cold, so that his wife broke into the school house and hit him on the head with a box because she was angry after eating. Le Jun is a servant under the shed and is embraced by everyone. On similar days, decades passed, "from the beginning of each Dan, I gave the group classics and recited them tirelessly for hundreds of times." For example, Le Jun, a teacher in Ye Mengde, often went hungry, worked hard for decades, and lived a harmonious and intimate life with children, which also reflected the general situation of Mongolian education in the Song Dynasty.
