Dear Wei Huanjing,

I am very excited to receive your e-mail. I am interested in your questions.

There are many rivers in our city. Ming Jiang River is one of the longest rivers. But the water in the river isn’t as clean as before. This is because people cut the trees down a lot. As we know, trees can keep the water much cleaner. On March 12th, We often plant some trees on the hills. More and more trees are growing. I think the water is becoming cleaner and cleaner.

Looking forward to meeting you soon.

Yours,

Li Zhiyuan
