Tujia, Chinese pinyin: dàn jiā In the old society, the water residents and fishermen distributed in the tributaries of the lower reaches of the Pearl River were called Tujia. The origin of Tujia family can't be verified. One is the early southern Han nationality whose families such as Guangfu and Hakka in the Pearl River Delta reached the Pearl River Delta; First, it is a special folk body formed by the southern water people such as Gu Yue or Gu Li who were rejected by the land people and drifted at sea for many years. It is not an independent nation, but a collective name of coastal water residents in China, belonging to the Han nationality. Some people think that this title is because of this family, family, family, family, family, family. This is a good example, and we can use this example to illustrate it. Some people think that Yi family members struggle with the wind and waves at sea all the year round, living in a sinister environment and having a unique means of making a living. Their lives are insecure and fragile as eggshells, so they are called Yi family. Their family is mainly engaged in fishing and water transportation in coastal ports. They have been floating around the house for generations, keeping company with the water and fighting the wind and waves for a long time. They are called the greatest navigators in ancient China, also known as "domestic thieves", and "Gypsies" at sea because they are adrift at sea. In the early days of liberation, they almost became the 57th minority in China.
