Abstract: It is hoped that the knowledge and achievements of public anthropology should be publicized，that the ethnography should be written with profound thoughts yet expressed in a popular way so that it may become a cross-discipline and even public reading material with the help of mass media.Public anthropology is one that thinks for the public，thus it should possess a strong sense of public concern，serving the public，appealing and defending for public interest.Taking public field as a normalized new research subject，public anthropology will no longer limit its field investigation to traditional small societies or villages；instead，it can be any public field in modern society.Public anthropologists should not only put forward suggestions，rather they should turn their identity from a trouble-solver to a decision-maker，and from a participant to an administrator.Researchers of public anthropology should become part of public intellectuals.With strong social and moral responsibilities，they should not only spread knowledge of anthropology and cultural diversity，but also make full use of their professional knowledge to guide values in the new era，showing their great concern to human destiny.

Key words: public anthropology, public, public field, public issues, public affairs, public intellectuals
