loneliness, and those who take care of their grandchildren may feel burdened by this responsibility. Reform Over the past few decades since the economic reform in 1978, the state of the People's Republic of China has taken steps toward reforming the hukou system by implementing a variety of reform policies. 1979-1991 can be identified as the first reform period. Specifically, in October 1984, the state issued a document called "A Document on the Issue of Peasants Settling Down in Cities", which required local governments to integrate rural migrants as part of their urban population and to enable rural migrants to register in their migrant cities. In 1985, the state also implemented a policy called "Interim Provisions on the Management of Transient Population in Cities", which allowed rural migrants to stay in their migrant cities even if they had neither changed their hukou status nor returned to their original rural residency. In the same year, the state also published a document called "The Regulations on Resident Identity Card", which enabled rural migrants to work in cities even if they did not carry an identity card of urban status. However, what followed these policies was not only a 30 million rural-to-urban migration, but also a phenomenon in which many false urban identity cards were sold to rural migrants for gaining urban benefits. It hence stimulated the state to implement another policy, "A Notice on Strictly Controlling Excessive Growth of 'Urbanization,’” in 1989 for regulating rural-to-urban migration. Under this policy, rural migrants were monitored again. 1992-2013 can be identified as the second hukou reform period. There were various kinds of reform implemented by the state. Beginning in the late 1980s, one was to offer a "lan yin", or "blue stamp", hukou to those who possessed professional skills and/or ability to make some sort of investments (at least 100 million Renminbi yuan) in specific cities (usually the big cities such as Shanghai), allowing them to live in cities and enjoy urban welfare entitlements. This "blue stamp hukou" was then conducted by many other big cities (including Nanjing, Tianjin, Guangzhou, and Shenzhen) in 1999. The second kind was not applied to big cities but to certain selected towns and small cities. In 1997, the state implemented a policy that granted urban hukou to the rural migrants who had a stable job in their newly resided towns and small cities. Meanwhile, according to two 1997 government
