Afew years ago, they were ordinary Chinese mothers; then, their understanding of universal love was simply "taking care of one's own children first, and then extending the same type of care to others'children.6 From establishing a nongovernmental, loving-care assistance QQ group','in 2010, to formally registering an assistance service, named "Home of Love," in 2012, the women have raised two million yuan (US $326,400) and helped more than 50 poor and seriously ill children. 展开更多
