So far I have already made a few friends and had some traditional English food there. But after having three days of hamburgers, sandwiches and potatoes, I thought none could be more delicious than Chinese food, especially my favorite --huo guo. You can't imagine how excited I was when I got to know that there was going to be a free meal of hotpot to welcome the new students. On the way to the canteen, I seemed to smell huo guo in the air. To my surprise, when I stepped into the room, I didn't see any sign of huo guo. Where was it? With many questions in my head, I sat down to have the free meal. After talking with an English girl, I got to know that Chinese huo guo is completely different from hotpot. Chinese huo guo is written in two words-hot pot; and hotpot, one word, is a traditional English dish. Hotpot is made from mutton and onion. On the top are pieces of potatoes. People put it in the oven all day in a heavy pot on a low heat. It takes very little effort to prepare. You can often see it at parties in the UK because it's easy to prepare for a large number of people and is not expensive. Hotpot doesn't taste bad. However, I still miss huo guo-hot pot, two words!
