"I wasn't so happy in my childhood. My parents broke up when I was six. Before, I was a very active, naughty child, but after my father left me I stopped talking. I became very good at hiding my emotions. I felt so ashamed of telling others that I didn't have a father, because that was not common in the 1960s. People didn't break up - even if they didn't love each other - in traditional Chinese families. Not like today."
