Tu Su wine is a kind of wine that was drunk during the Spring Festival in ancient China, so it is also called Nianjiu. Tu Su is a kind of house in ancient times. Because it is brewed in this house, it is called Tu Su wine. Its formula is prepared by soaking rhubarb, Atractylodes macrocephala, Cinnamomum cassia twig, Saposhnikovia divaricata, Zanthoxylum bungeanum, aconite root, aconite root and other Chinese medicines in wine. Tu Su is very particular about drinking. An unconventional order of the young and the old, the whole family uses the same small wine cup to drink from the youngest generation and pass it on to the elders in turn, which means to gather the essence of young people and offer them to their elders to wish them a healthy life. No wonder there is a saying in Su Zhe's "In addition to Japan": "I drink Tu Su at the end of every year, but I don't feel that I have been over 7 years." Tu Su wine is slowly poured into a special flat wine. Men use their left hand and one hand (in ancient times, warriors could not occupy their right hand, so that they could take a knife to prepare for war at any time), while women hold cups in both hands and drink the wine in three times.
