I went to the Chinatown market in London last Sunday. The first thing I did was to go to one of the Chinese green grocers’ shops. As soon as I entered the shop, I smelt mixtures of Chinese spices and saw the new season’s fruits. My son wanted a bag of sweets, so we popped into the shop next door which sells many kinds of candy.

There’s a lot of noise in the Chinatown market and you will see many tourists too. There are a lot of cars and trucks that never stop beeping. While people are loading and unloading their goods, most of them have their cars and trucks parked in the middle of the road. This causes great inconvenience for other drivers. Can you imagine that?

After we had done all our shopping, my son and I went to a restaurant for lunch. We enjoyed our meal very much. But the shopping made us both very tired at the end. We headed down the road to catch our bus home. My son and I enjoyed riding in the bus. We also enjoyed looking at different buildings and people walking by dressed in fancy outfits. Although Chinatown can be a busy place to shop, I do enjoy going there now and then. I can buy some of my necessities, and I can also look and browse around the other shops and department stores where I can indulge (使沉迷) myself with some nice things. Chinatown is located in the heart of central London where you can find tons of shops and other places to amuse you. And for me, I certainly don’t mind going back there again soon.
