Chen Songying, with four chairs reserved for her husband and three children who left home to work, sits in her farmland in front of her home in a village of Shizhuan town, Shikang city, Northwest China's Shaanxi province, August, 29, 2011. In the process of urbanization, more rural people in China leave villages to work in cities with most working as migrant workers. The statistics of National Bureau of Statistics shows that China already had a total of 230 million migrant workers in 2009. As it is not easy to take families to settle down in cities, the migrant workers from rural areas have to leave their kids, wives and parents in their rural home, which makes the population of some rural areas mainly made up of women, kids and elderly people. A survey conducted by China Agriculture University shows that there are about 87 million people left behind in rural area, comprised of 20 million kids, 20 million elderly people and 47 million women.
