Last Sunday Li Lin，one of my classmates，and I go to a bookstore. At a counter we noticed that the foreigner was talking to a clerk，and the clerk didn't understand what the foreigner said. So we went up to the foreigner and was asked if he needed help in English. After known what kind of books he really wanted，we took him to the shelf which he was looking. He was interested in Chinese folk music deep. We gave him some advices on what to choose. The foreigner picked some music tapes with his help. He gave his sincere thanks to us and left，satisfied and happily.
