Public interest litigation（PIL）in China has made tremendous progress both in terms of quantity and types since the 21st century，but different types of PIL have witnessed different development trajectorys. Personal PIL starts as a pioneer of a new time trend，but ends in being totally forgotten by law. Social organization PIL is a later player compared to personal PIL，but eventually it is the state agency PIL that becomes the mainstream of PIL in China. PIL in China becomes legalized and maintreamlized in last two decades，but the strong rise of state agency PIL has made PIL become more and more nationalized. Only by leaving the necessary development space for personal PIL，can China’s PIL develop more healthily.
