Xi Shi Tao Li is full of mulberry, Dong Tan Long Snake is a model. It contains allusions.

teacher: that is, "teacher". This is related to Liu Zhuang, the Emperor of Han Dynasty. According to Volume 8 of the Appellation Record, "Emperor Hanming honored Huanrong with a teacher's ceremony, and was fortunate to be in Taichang House, so that Rongrong sat in the east and set up several places. Therefore, the teacher called the teacher. " Tao Li: It's a synonym for students. During the Spring and Autumn Period, the minister of Wei was well-informed and knowledgeable. Because he offended Wei Wenhou, he ran to an old acquaintance's house in the north to escape. This friend's family is not rich, and Zi Zi doesn't want to burden his friend's life, so he wants to open a school and accept some students to teach, so as to make a living. Friends are very supportive of him, so they vacate two vacant rooms as classrooms. Students admitted by Zizi are rich and poor, and anyone who wants to learn can worship him as a teacher and treat him equally. There is a peach tree and a plum tree in this museum. All the students who come to school kneel under the peach and plum trees to recognize Mr. Zi Zhi pointed to the two trees that had already borne fruit and said to the students, "You should all study hard and blossom and bear fruit like these two trees. Only with high learning can we make a great cause for the country. Mulberry: In ancient times, mulberry and catalpa trees were often planted beside the house. He also said that the mulberry and catalpa trees in his hometown were planted by his parents, and we should pay tribute to them. Later generations use "mulberry" as a metaphor for their hometown-Weisang and catalpa, which must be respectfully stopped. Dong Tan: The son-in-law, also known as "Dong Chuang", originated from the legend that the famous Chinese calligrapher in the Jin Dynasty was naked. According to legend, during the Jin Dynasty, Chi Jian, a teacher, had a lovely daughter, Xuanxuan, who was smart and young. Xi Taifu heard that the sons of Prime Minister Wang Dao were all handsome, so he intended to marry his children in-laws. Prime Minister Wang also agreed to this marriage. One day, Dr. Xi sent a guest to the palace to choose a husband with his own handwritten letter to Prime Minister Wang. After reading the letter, Prime Minister Wang said to the public, "My sons are all in the east wing. Tell Dr. Xi that you can choose any one!" After visiting the East Wing, the public thanked Cheng Xiang Wang Dao and rushed back to Longfu. He replied to Taifu, "Seeing is believing, and I didn't know until I got to Wangfu that the sons of Prime Minister Wang were really good-looking and handsome. I heard that I chose a son-in-law for you, and all of them entertained guests. Some of them were still a little stiff. Only a young man was lying on the east bed with his stomach bare, as if he had never heard of such a thing. " Who knows, after hearing this, Dr. Xi said happily, "Let's choose the one who has a bare stomach and an east bed as the husband. I am proud of this. He will definitely be a good son-in-law in the future. " Chi Jian, a teacher, later learned further that this young man was Wang Xizhi, so he married his daughter Xuanxuan to him. Dragon and snake: at the beginning, it is a metaphor for extraordinary people, and it also refers to all kinds of people, and dragons and snakes are mixed. Model: the meaning of model. In the Song Dynasty, Sun Yi compiled a series of stories about showing children during a trip to Zhai, saying, "Confucius' tomb was filled with letters, and Duke Zhou's tomb was filled with molds, so later generations thought it was a model."
