Dear sir,
I am a tourist from the UK. Yesterday I visited the park and had a wonderful time there. But when I returned to the hotel, I found my wallet missing. There was a lot of money in it, and above all, there were also my passport and flight ticket. Naturally I was very worried． In the evening , the hotel manager brought a boy to my room. The boy handed me my wallet. I thanked him and offered him some money. But he politely refused． Form the manager, I learned he is a schoolboy of your school and his name is LiHua．
Yours,
John Smith
