Guangzhou is the capital of guangdong. it is the biggest city in south china. and it is one of the most important cities in guangdong.
The population of guangzhou is more 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.
