What is the gift for girls from Dai boys in Banna?

String girls Dai boys "string girls", which is called "Yue Sao" in Dai language, must bring flashlights, bamboo flutes and blankets. Go to the bamboo downstairs of the girl's house and play the bamboo flute to express your feelings. If a girl is interested, she will wait for her parents to sleep and quietly go downstairs to talk to the young man. As the night gets colder and colder, the young man will wrap the girl in a blanket and take her to the forest near the village for a secret talk. There are several girls spinning on the spinning field, and the young man takes photos one by one with a flashlight. When he finds the right one, he will play the flute and piano beside her. If a girl is interested, she will take out the small bamboo stool hidden under her skirt and give it to him. When chatting late into the night, the young man will lift the blanket and hold the girl in his arms. If the girl is careless, then the small bamboo stool will not be pulled out for him, and the young man will live in vain. Packet loss is a way for young Dai men and women to fall in love. During the Songkran Festival, young men and women stood on each other's side, twenty or thirty meters apart. The girl throws the small sachet in her hand to the man first, and the man takes it and throws it back. The one who can't catch it has to throw in the towel and give the other a gift. In fact, girls throw it to the right person with a purpose, and the other person throws it over. After several times, the girl threw the sachet high and far, and the knowing young man pretended not to admit defeat. He went to find the girl and gave her a gift prepared in advance, so they both left the bag-dropping field and fell in love in the forest by the river. In recent years, this method has been extended to a symbolic group game to express a warm welcome to distant guests.
