Nan'ao Peninsula is located on the edge of Dapeng Bay in the eastern part of Longgang District, Shenzhen. Since ancient times, Nan'ao fishermen have their own unique etiquette for getting married. The first is engagement. When a young fisherman reaches the age of marriage, he will give a deposit to the woman after being introduced to a partner. After getting the woman's birth date, he will put it on the altar on the boat and burn three incense sticks. If there are no broken dishes within three days, the engagement is considered successful. Then it is time to prepare the wedding. First, the woman's family will be given a big gift, usually ten plates of pigs, chickens, fruits, cakes, etc. The gift-giving procedures are completed by docking the man's boat with the woman's boat. The man's family must decorate the new room in the cabin, including decorating the new bed, hanging the wedding curtain, "saying four sentences", singing the "hanging curtain song", and the children going to the new bed to grab the fruit. Three days before the wedding, the woman is waiting to get married at home, and her parents and daughters all sing the "marriage song". The man prepares wedding items, and also sells flowers and sings the "singing flower song". There is also the custom of "selling red". Welcoming the bride is the 0 of etiquette. On that day, the groom wears a felt hat, a long gown, two red belts around his waist, silver beads in his temples, and a big red flower on his chest. The bride wears a red robe, red flowers in her temples, and flower shoes. There is a gong and drum band on the groom's boat, and they row the boat to dock with the bride's boat at an auspicious time. After the bride is taken on board, the bride and groom burn incense and light candles to worship the sea, kneel down to worship their parents, the bride sings a song of leaving home, and the sisters on the dowry boat sing a song of sending off the bride. Finally, a banquet is held on the man's boat for two days. Although the marriage of Nan'ao fishermen has changed to taking place on land, some of the previous customs are still used today. The marriage customs of Nan'ao fishermen are unique customs formed by Nan'ao fishermen's long-term life at sea. They have certain historical value and are also of certain value to the study of marine culture.
