"Cihai" has a "good man" entry, which is the old name of water residents. There is no entry for "Jia Jia", so it may be more accurate to call it "Jia Min". In fact, the Yi nationality originated from the ancient Nanyue nationality, taking the boat as the room and water as the land, floating in the rivers and seas. The most common is the Pearl River in Guangdong, which is distributed along the coast of the South China Sea and even on islands in South Asia. People have always been discriminated against. During the Yongzheng period of the Qing Dynasty, only Yi people and Qi people were allowed to be listed as one household, but they were still regarded as untouchables. It was not until the early years of the Republic of China that the people were equal to the people. Only after liberation did the people turn over, become masters of their own affairs and embark on the road of happiness. In history, there was a large population at the seaside of Shanghai Estuary, but due to the continuous "Haikou" and "village humanization", there are only three villages left, namely, fishing new village, fishing old village and Baisha Menxia village, with a total of 205 households and 986 people. They still speak Liao Jia dialect of Guangzhou dialect, but they are also familiar with Haikou dialect. In terms of customs, Haikou people are roughly the same as Haikou people, but they also retain some unique characteristics. Place of residence: Haikou people have been living in the sea and drifting. Sometimes, "Baigeliao" is built on the sand bar of the beach to settle down. People live on the upper floor and the water is below, which is convenient for going out to sea to make a living. After liberation, some people settled on the land and built tile houses and small buildings. For example, someone moved to the east of Haikou port gate because of the construction of Binhai Street and salt stove seaside fishing team, which is called Yuxin Village. Clothing: Haikou women's clothes are tight and slim. The right side of the coat is buttoned, and the sleeves are often lined with brightly colored cloth. A silver hairpin is inserted in the bun, and a Yu Pei tortoise shell bracelet. Marriage: In the past, most people used to find the media as matchmakers, and their parents arranged it. Before getting married, brush the boat clean, paint it with new oil, and put on red wedding couplets. On the wedding day, brothers and friends' boats get together and have a good drink. Listen to folk songs before entering the bridal chamber. The name of the child is also very strange. Boys like to use "Zi" and girls like to use "Gu". When children grow up, they are often named after "dragon and phoenix, colored beads and waves", indicating family affiliation. Beliefs and taboos: The Virgin Mary, brothers, Changhuagong and General Jiang after the sacrifice of Haikou people are all sea protectors. When a ship sails or stops, burn incense and pray to the gods to protect the safety of water navigation. Haikou people have many taboos. Don't cross the golden roof of the bow when boarding the ship at ordinary times. When fishing, you are asked to be seated in time when eating, and you can't answer "No" or "You eat first". If you say so, it is unlucky, which means that fish will fail if they don't eat the bait and can't catch the fish. Do not cut the tail, that is, leave a back road, so as not to cut it off later and catch no fish. In addition, pregnant women are not allowed to cross another ship or enter another house before the full moon.
