Sia wine is made from highland barley, barley, and sorghum, which are cooked and mixed with distiller's yeast, put into a jar, and covered with grass. When drinking, first pour boiling water or clean water into the jar, and then use a thin bamboo tube to drink. After relatives, friends and distinguished guests arrive, everyone takes turns to drink, add water after drinking, and then eat the dregs of the wine until the taste is light. It is commonly known as "with the dregs and water, one is drunk and two is full." When drinking wine, a drinking song is sung, and the guests and hosts sit side by side. Sit down and take turns singing in antiphonal style, while the drums and music play, making it very lively.
