the positive quality is composed of a series of positive characteristics, and it is the intelligence which people rely on to seek happiness. So far, the research at home and abroad has focused on two aspects----its content and its cultivation mechanism. Through the summary of these researches, this article holds the opinion that foreign scholars have made quite profound and systematic researches of the theoretical basis in bout the two aspects, and have provided important guidance for practice. Yet the deficiencies are these researches have not given enough consideration to cultural factor, and lack of attention to special groups in the cultivation section. Domestic researches start relatively late, and most of these are about the introduction of western theory and some general advices for cultivation, and the research of localization basic theory is relatively weak. Explore positive quality and its cultivation under more specific culture and group background will be a direction of the future research.
