Things have changed a lot this year.
Old houses disappeard,new buildings are being build quickly by the workers.
Look at the river,last year ,it was seriously polluted,but now,it's clear and blue again,we can see fishes swimming happily.
People are busy planting more trees to make the air fresh.
Our life become better and better.
