I took a trip to China a few months before. It was a wonderful experience which I couldn't really describe it. We spent three weeks visit Beijing, Shanghai and several other tourist attraction. The close we approached the centre of China, the more I liked it. Then we went to Hong Kong last week, where I think is different from Beijing. It is noisiest and busiest place I have ever seen. And another thing that give me a deep impression was the people—they were so friendly. Anyway, the trip itself was interested. I can't wait to leave to China again.
