The human beings destined to exist on the universe and live on this magical world，are obligated to promote the sustainable development of society and defend the virtues of mankind.Only when we strive for social innovation which is thoroughly powered by the belief “following our heart and defending virtues of mankind” can this obligation be genuinely fulfilled.Social innovation helps to eliminate bad factors which do harm to the development of “bonum commune”.In a sense，the history of human beings' development is regarded as the history of social innovation.So far，people have developed social innovation activities by means of institution，technology and value.In the era of big government，though，most social innovation activities were monopolized because of the public policies implemented by government.However，in the 1990s，the people's power which represented Social Entrepreneurship and Social Business arose rapidly with the gradually powerlessness of government.Thus，the trend of social innovation was triggered when it came to new epoch.In response to this trend，I have developed a serious of social innovation activities in the fields of community construction，environmental production，public welfare，organic agriculture，and political election.Besides，I also designed courses for Ph.D.and postgraduate students on social innovation education in Doshisha University，in 2005.
