The outstanding characteristics of marriage customs in Song Dynasty should be sorted out.

Yi people think it is impolite to talk about love at home, and they must talk about it in the girl's room. Girls' rooms are generally public houses. In the girl's room, the girl can stay and meet her young men. They sleep in the same bed. Even if there are several young men and women at the same time, everyone is not surprised and unconstrained style. However, according to Yi rules, girls and boys share the same bed and can only talk, but not start work. If you deviate a little, you will attack them in groups.

Yi girls will be baptized by adults when they are seventeen or eighteen. Mother and female elders choose auspicious days, burn incense, pick clean water, and wash the girl's body, waiting for her girlfriends to start changing into the white dress she wore as a child and the black dress that marks an adult woman, and saying some words of praise and blessing while changing.

Then she was sent to live in a girl's room specially built for her, and she began to associate with boys.

Girls' rooms vary in size, big and small, and can accommodate a dozen to three or five people. They are usually built at the head or end of the village. One is to facilitate young people to know girls, and the other is to avoid affecting parents and elders in the village. The girls go home to work during the day and spin, weave and embroider in the girls' room at night. Some girls will also prepare some snacks such as cigarettes, candy and melon seeds, and when the boys come to meet, they will sit and chat together.

Whenever night falls, girls will dress up and wait for the arrival of their favorite boys. After the boys came, they got to know each other through conversation, and then formed a circle in the girls' room, singing love songs and dancing happily. When you are tired of singing and dancing, sleep in the same bed with the girl you like and wear a dress, but don't have any ideas, or the girl will get up and attack. At dawn, the boys will wake up early, meet again, and then quietly leave the girls' room. At this time, the girls will go home and start their day's work.

The girls' room is also a blind date place. The girl went to the concert, and her mother had to cook for her future son-in-law. After young people get to know each other at the concert, young men and young women must live in the girl's room and be entertained by the girl. And parents can't show up, so they can only peek through the door. That night, the girl and the boy lived together and further complained to each other. At dawn, the young man quietly left. If the man likes it, he will soon send someone to propose. If the man doesn't move for a short time, it's over. If the man proposes to get married, the woman can refuse. No matter which side doesn't want to, wait until the next song and dance, and then choose another one.
