I first met Li Meng at a friend birthday party in five years ago. Then I invited Li Meng at my place. We listen to my CDs together and soon became good friends. Three years ago, Li Meng’s parents invited I to spend two wonderful week in Qingdao with them during the summer holiday. Li Meng and I loved walking along the beautifully beaches there. Last year I was ill but had to stay in hospital for a week. Li Meng came see me every day. Then, her father changed jobs and they moved to another city. Since then we haven’t seen each other much, but we’ve kept write to each other.
