guangzhou is the capital of guangdong. it is the *ggest city in south china. and it is one of the most important cities in guangdong.
the population of guangzhou is * than 700 million. just like many cities， there are a lot of cars， buses and trucks. so the air in the city is not clean. guangzhou is a noisy and crowded city. but i like it best. because guangzhou is my home.
