The summer holiday begins. I am very happy. Last week， I tr**eled to Zhuhai. Its a small but beautiful city. The streets are clean and the buildings are huge. The traffic of Zhuhai is good. There is almost no traffic jams here，because the transportation system is good. Macau is on the opposite of Zhuhai.We can even see the cars running in the streets of Macau. I hope I can step into Macau to visti this magical city.
