Lanzhou Waterwheel Expo Park is a famous business card of Lanzhou city culture, which shows the long history of the Yellow River culture. The large and small water trucks in the garden introduced how ancient people invented water trucks to carry water and irrigate water, as well as water trucks that they could experience personally. Waterwheel park on the Bank of the Yellow River, with dense shade, overflowing fragrance of flowers and murmuring sound of water, is a good place to go indeed! ___________
