The marriage custom of the Tanka in Zhapo is a unique water culture phenomenon in the lives of water dwellers in Zhapo, Yangjiang City, Dongping Town, Yangdong County, Shaba Town, Yangxi County, and Yangchun Inland River. When young men and women reach the age of marriage, whether they have their own lovers or are introduced by others, they must ask a eloquent matchmaker to lobby between the two families to achieve their marriage purpose. After lobbying and obtaining the consent of both parents and elders, they will choose an auspicious day to get married. This marriage takes at least a month and at most a year from the beginning to the completion of the marriage, during which it is full of the unique flavor of the Tanka fishermen's water life. For example: complicated etiquette, decorated gift boats, unique costumes, headdresses, hairstyles, picking up the bride in the middle of the night, and singing saltwater songs. It shows that the Tanka fishermen attach great importance to marriage and their pursuit and hope for a happy and beautiful life.
