Marriage introduction: Qiang people advocate monogamy in marriage. There are women who marry men, and men who marry women upside down. There is a saying in the Qiang area that "a son-in-law who comes to your door is like a bought mule." . Marriage plays a very important role in the lives of the Qiang people. The traditional wedding custom is a solemn and complicated process, but it can be roughly divided into two stages: engagement and marriage. The engagement process is divided into three steps: "open wine", "small fixed wine" and "big fixed wine". From the engagement to the wedding as scheduled, the time often spans several months or years. There are five days before and after the wedding, including the "Flower Night" and the "Main Banquet", also known as the "Main Wine" and "Thank You" ceremonies.
