In Dai marriage, it is common for the man to marry into the woman's family. Before marriage, young men and women are free to socialize and fall in love. The following are common: social love: "Yao Sao" in Dai language, "Chuan Girl" in local Han nationality; throwing bags; singing folk songs. After the relationship is confirmed, both parties will send each other tokens of love. The man tells his parents that he will ask a matchmaker to go to the woman's family to formally propose marriage. As long as the children agree, both parents will not obstruct. After the engagement, a "good day" must be chosen to hold the wedding. The wedding is usually held at the woman's home. The main ceremony is tying the string, which is called "Shu Huan" in Dai language, which means "tying the soul". After marriage, the man lives with his wife and marries into the woman's family. Generally, from the day of marriage, he will live in the woman's home for three years. Then, with the consent of the woman's family, the husband will take his wife back to his own home for three years, and then return to his wife's home for three years. This cycle repeats until he inherits one party's property and establishes a new family.
