Xiaolu Guo said this quote
“ Then he asked my age and I asked his. That's the tradition in China. If we know each other's ages we can understand each other's past. We Chinese have been collective for so long, personal histories are not worth mentioning. Therefore as soon as Xiaolin and I knew how old the other was, we knew exactly what big shit had happened in our lives. The introduction of the One Child Policy shortly before out births, for instance and the fact that, in 1985, two pandas were sent to the USA as a national gift and we had to sing a tearful panda song at school. 1989 was the Tiananmen Square student demonstration. Anyway, Xiaolin was one year younger than me, so I assumed we were from the same generation. ”
