There is no logical relationship between "spring warming" and drinking "Tu Su". The word "Ru" before "Tu Su" (it should be "drinking" or "drinking", etc. ) is a mismatching. Then, according to Tu Su's original intention, we can try other explanations to see if they are more suitable.
According to Ci Hai, "Tu Su" has three meanings: ① wine name. ② Grass name. 3 houses; Cao An. Song Shu Rousseau biography: "(Tuoba) Tao lived, was struck by lightning and fell down." Du Fu's poem "Huai Ye Han Tao" said: "I would like to go to the Soviet Union with me." Qiu quoted: "Sue, the home of the son of heaven."
The Tang Dynasty's Sui Ji Hua Li Yuan Ri Ru Note: "According to legend, it is the name of Cao An. Once upon a time, someone lived in a grass temple. Every year, except at night, they leave a patch, including a capsule, in the well. They take water until January and put it in a jar for the whole family to drink, so that they are not infected with the plague. Today, people have their own side and don't know their names, but they just call it' Tu Su'. "
This document is very important and helps us to understand the meaning of Tu Su. According to the above records, we can know: First, "Tu Su" is the name of a thatched cottage. Second, the famous doctor in this grass temple sent herbs to people to blend into medicinal liquor, which can avoid disaster after drinking. Third, the time is to send a pack of herbs on New Year's Eve so that people can drink wine during the Spring Festival. In this way, the three meanings in Ci Hai are closely linked.
After consulting more information, we found that "Tu Su" is not the proper name of the thatched cottage. According to the popular literature devoutly written by Han people, all thatched cottages are called "Patent Su". Then, why can Tu Su be extended to mean "house" and "home"?
In fact, "Tu Su" is a relic of ancient language, and "Tu" is an ancient Yue phonetic notation with comfortable pronunciation. "Tu Su" is an ancient name for tea (primitive tea), so it means flowers and plants. "Tu Su" means "hut", and:
Han's Popular Literature says, "The house is flat."
Guang Ya Shi Gong by Wei Zhangyi of the Three Kingdoms: "Tu Su, An Ye."
Guang Yun in the Northern Song Dynasty: "Tu Su, Cao An also."
