Yesterday, I went to a region to buy train tickets. When I was about to leave, I saw a foreigner come in. I thought he could speak Chinese, but then I knew he met some troubles. He wanted to take a bus to Hongkong and all he has was a paper that time, bus destination and destination were written. The problem was that there were four bus station in Hongkong, the ticket seller did not know which one he was to go. Therefor, I decided to help him. He wanted to the downtown of Hongkong, but he did not know which bus destination is in the downtown. So I asked the ticket seller about the information of bus stations. And then the foreigner ask several questions about time, bus station and others. The ticket seller explained to me and then I translated for them. Finally, he got his ticket. He was so happy that I can help. So did I.
