What has changed in Zhenbeitai? Please show an example. 2. Why can Yulin City be honored as a National Forest City? Great changes have taken place in Zhenbeitai. There are four great changes, such as shopping, environment, roads and hospitals. For example, people used to travel far to see a doctor. Now there is a new hospital in their town and they don’t need to travel far again. Yulin was once a sandy area with poor environment. For decades, people there have kept planting trees and fighting against desertification(荒漠化). It shows the spirit of hard work and love for nature. Today Yulin has more forests, fresher air and cleaner rivers. The city is greener and more livable. Imagine you are Li Rui, a student from Zhenbeitai.
