Introduction to the square: The wine-sipping square is dominated by the wine-sipping culture, which is an extremely important part of Qiang culture. Qiang people, regardless of age or sex, like to drink alcohol, but they never cause trouble after drinking. The Qiang people use highland barley, a unique crop high in the mountains, as the main ingredient, or combine it with barley, wheat, and corn to carefully brew jars of highland barley wine. There is a poem that praises: "Ten thousand pearls are collected in a jar, and the princes, generals and prime ministers all bow their heads. With both hands full, the sky pillar is sucked, so that the water of the Yellow River flows back." Among the people, there is even "Brewing wine on the edge of the Minjiang River" and "In the poles of wine" The folk song "Looking for the Yellow River" is sung.
