Xiao-Doing,
　　
　　I just read this very sad news from Google yesterday and I was shocked and I couldn't understand why it happened??? I have been felling really sad. I still remembered whenever I returned back to China, you organized the classmates together to wlcome me and I have always thought about you and LiLi. I would be very happy if I know that there is anything I could do to help your son and LiLi!! Ze-Yan from Sydney, Australia
