They are living in Beijing, but many of them are not the locals or they are not Beijing peoples. Among them, they are tourist, travelers, businessman as well as migrant workers. Although they have different purpose stay in Beijing ,but one thing in common：they are not a Beijing registered residence, they do not have Beijing Hukou.
The characteristics of the Chinese household registration system are as below：people are divided into agricultural and non-agricultural based on living region difference and the relationship of family members.
The Hukou system has four main functions: to prove citizenship; to help maintain social security; to control the population growth in the town; the local household registration department can master the more accurate population information. Hukou register system shows the legitimacy of a natural persons in the local life.
In January 9, 1958, the new China's first household registration management system,"Permanent residence registration ordinance of the people's Republic of China" promulgated. The law can restrict the flow of urban population and the famer immigrant into the city. This approach has played a positive role in the early days of the founding of the P.R.C.
With the development of social economy, the negative effect of the old household registration system is becoming more and more obvious. 1990s, China's market economy is booming up. According to estimates, in 1997 the national floating population has reached 1.1, the total population of China's floating population has been close to 2.3 in 2011.
In recent years, China has adopted various measures to encourage, support and guide the normal and reasonable flow of population. Along with the identity card, temporary residence permit, commercialization of house market and employment market, the subsidiary of the household registration system is reducing.
In 2014, after several decades, the debate over the reform of the household registration system and finally there is a real progress:Different scale cities began to implement differentiated settled policy. Policies allow for the ability and willingness of migrant workers and their families to gradually shift to urban residents.
Through the establishment of residence permit system, the agricultural transfer population can settle in city. The children of the migrate workers have chance to go to the city to receive education in urban areas. Children do not have to return to their birth place to take part in the college entrance examination. Workers have more opportunities to get skill training.
