Wang Mei: OK. By the way, there is another group of people down the hill. Are they also coming to plant trees
Worker: Yes. Many people are worried because the environment is changing, and they want to do something to help.

Wang Mei: Ms. Liu told us the wind blows the dirt and the sand here from the north. Nothing can stop the wind because there are not many trees left.
Worker: Exactly. A lot of rich lands in the northern area have turned into desert.
Li Ming: I suppose tree planting is very important work.

Worker: Yes. It’s fun and important to plant plants. Oh, and please
remember to put a little water in the bottom of the hole.
