I watched it today. It is an excellent movie. I am from the same generation of Dr. Wang grew up in China during the Cultural Revolution I saw worse killings and human sufferings during the time. And suddenly in 1977, we had the chance to go to college through an entrence exam (Gao Kao). I was in the same situation like Dr. Wang: We had to teach ourselves the entire high school math, physics and chemistry in two month to get in. The story is so real to me. Exactly like Dr. Wang, I had only $50 in my pocket when I came to US to pursue my Ph.D in a different field. The story touches my heart.
