1992年,我去了美国华盛顿威尔逊研究中心,作为职位博士进行访学。从一开始,我就对他们的教学方法感到吃惊。我的老师叫裴宜理,研究方向是中国群众运动史。她给我讲了民国时期上海工人运动到“文革”这一段历史。我到她那里起先是希望学习关于这段历史的系统知识,不料一堂课下来,我一头雾水,不知所云。 In 1992, I went to the Wilson Research Center in Washington, DC, to study as a Ph.D. candidate. From the very beginning, I was surprised at how they taught. My teacher is Pei Yili and my research direction is the history of mass movement in China. She told me about the history of the Shanghai Workers' Movement during the Republic of China to the “Cultural Revolution.” When I first came to her, I wished to learn the systematic knowledge about this history. Unexpectedly, I fell into confusion and lost my knowledge.
