As the first sociologist in business school in China, I had once faced tremendous legitimacy problem: what does sociology can bring to business school? Now I have demonstrated the value of sociologists to them. By persuading the rich and powerful to be responsible and benevolent to the poor and weak, we can contribute to social progress. Of course, the prerequisite of doing this is to be accepted and respected by students. I really benefited from the training in Berkeley which taught me knowledge, insight, and care to the disadvantaged.
