Dear Sir/madam,
I am Li Hua, an exchange student from China. I am writing to ask you to look for a Chinese student.
Yesterday, my roommate Tony was on the way to the classroom when he fell down and could hardly move. Just at that moment, a Chinese girl came to him. She gave him first aid and called an ambulance. Thanks to the kind girl, Tony was sent to hospital in time. But the girl left quietly before Tony could express his thanks. The girl is about 18 years old and of medium height with short hair. Tony is eager to meet her to express his sincere thanks. Could you please help find her?
Looking forwards to your reply.
Yours,
Li Hua
