Wu Ningkun, author of a new personal and political memoir, A Single Tear, talks about surviving three decades of Communist rule in China. Wu was born in China, went to college in the United States, and returned to China in 1951 with hopes that the new Communist regime would benefit his country. Instead, he was labeled counter-revolutionary for teaching works by Western authors and sentenced to serve time at various labor camps and prisons. He now lives in the United States with his family.
