Thirty y ago, Wuxi was a small but very lovely c . The sky was always blue and the air was c . There w many beautiful rivers around it. There were lots of flowers and trees too. People went to work by bus, by bike or on f . There was no pollution.

Now Wuxi is g bigger and more modern. But it's not as nice as before. Smoke from factories and cars makes the air dirty. Rubbish m the streets messy.
