My hometown is Zhengzhou, which is not only a modern city, but also an ancient city. Before liberation, Zhengzhou was a desolate small city, with muddy roads everywhere, and pedestrians were blinded by the dust that came with the wind on sunny days. When it rains, your feet will be wet and muddy. Sandstorms also frequent Zhengzhou, where yellow sand is like countless yellow insects, covering the sky. After liberation, great changes have taken place in Zhengzhou. The straight asphalt road replaced the muddy dirt road, and the streets were planted with drought and earthworm, covered with branches and leaves, and the whole city was shrouded in a green ocean. Zhengzhou was called Greentown. In recent years, the sandstorm that once ravaged Zhengzhou has become smaller and smaller, the sky in Zhengzhou has become bluer and bluer, and Zhengzhou has become more and more beautiful.
