I led the research team that did field survey about the "ant tribe" survival situation in Beijing,Shanghai,Guangzhou,Wuhan,Xi'an,Chongqing,Nanjing from March to November 2010. The socio-economic status of "ant tribe" and the attitude of social justice have been studied. The results show that "ant tribe" is the descendant of civilians and the poor,they can not get more social resources and financial assistance from their family,but highly educated,they have strong confidence of their future success. Such strong contrast makes the "ant tribe" has higher social injustice. In psychology,"ant tribe" take psychological defenses to get inner balance. In behavior,"ant tribe" change their level of performance to pay or income,emphasis on individual effort and hard work,and tend to express their interest demands throughout opening way,such as internet. <<
