Chinese migrant workers like Long , are heading home . They are attracted by better economic opportunities inland . Once one of the 250 million Chinese farmers that left behind their families to forge a living in the coastal factory towns , the 37 year old lives back in his ancestral village of Kongbai , a jumble of 200 timber houses that cling to the side of a valley in southeast Guizhou , one of China 's poorest province . Long wants to preserve village 's ancient silversmith trade . Does n't want people to work in factories .
