Nanjing is a beautiful city in Jiangsu Province. It’s clean and tidy most of the time. But sometimes it’s dirty. There’s some black haze(雾霾) in the air because smoke from the factories and cars makes the air dirty. We must move the factories away from the city. We can take the bus or metro to school. Dirty water makes the fish dead. Some people like throwing the rubbish everywhere. So sometimes the streets are messy and dirty. I hope they can put them in the bins. If some people don’t obey the rules(规则), we can call 12369. Let’s try together. Our city will be more and more beautiful.
