The term "migrant workers" was first put forward by sociologist Professor Zhang Yulin in 1983. Migrant workers, also known as migrant workers, simply refer to farmers engaged in non-agricultural industries, that is, groups whose status as farmers has not been transformed but engaged in non-agricultural industry production and operation in cities and towns. On the one hand, "migrant workers" have the identity attribute of farmers, on the other hand, they are engaged in industrial labor. It is reported that at present, many industries in China are mainly migrant workers, among which 90% employees in the construction industry, 80% employees in the coal mining industry, 60% employees in the textile service industry and 50% employees in the urban general service industry are migrant workers. The number of migrant workers in China has reached more than 94 million, and it is growing at a rate of 5 million every year. In 2005, more than/kloc-0.5 billion farmers went to work in cities, and two-thirds of industrial workers came from rural areas. However, due to the existence of "dual social structure", migrant workers have always been in a discriminated social position and become vulnerable groups, and their legitimate rights and interests are often not effectively guaranteed, which has become one of the main factors affecting social stability. Since the 1980s, with the wave of reform and opening up in China, more and more rural surplus laborers have moved to cities, pouring into towns in the form of huge floating population, pursuing the "urban dream" that generations have been looking forward to, and the special social group of "migrant workers" has emerged. While migrant workers make a living by their own labor, they also provide low-cost human resources for the development of the city and play an important role in the construction and prosperity of the town. Embarrassed, however, under the same roof of the city, migrant workers are obviously three points shorter and three points lower than urban people, and their social status is not proportional to their contribution to society. Protecting the rights and interests of migrant workers has become a very heavy and sad social topic.
