Dagong is a pledge of love woven with vines and bamboo splits by young men of the Dulong ethnic group in Nujiang, Yunnan Province. The exquisitely-made unique Dagong is about 15cm in size and disc-shaped. When a young man takes a fancy to a girl, he will fill up the Dagong with food and then hang it in front of the house of the girl’s family in the still of night. The girl will guess who the young man is from the style of the Dagong. If she also likes the young man, she will take the Dagong on her, meaning that she has had a boyfriend. On the contrary, she will hang the Dagong where she found it for the young man to take it back.
