Yifan’s best friend at kindergarten is Xuanxuan, our neighbor. He had Xuanxuan visited us tonight. The two kids spent great time together drawing trains, and building trains using Lego. Two kids can talk and can share happiness, and can understand things that only makes sense in their world. China really need to think about changing its one child policy. I don’t know how this half century recorded in history.

Their drawing of the Shanghai Metro is not bad.
