The old Lanzhou waterwheel tells the story of the life of Lanzhou ancestors. To understand this dusty memory, the Cultural Square in the waterwheel Exposition Garden is the best place to go. Traveling among the ancient buildings, tasting a bowl of "hot winter fruit" and a dish of "brewed leather". In the local rhyme, the cultural square gives people a taste of Lanzhou's folklore, Lanzhou's history, and Lanzhou's centuries of brilliance. Waterwheel Park - "reproducing the brilliance of Lanzhou Waterwheel Plaza is the most pleasant part of the Waterwheel Expo Park - "Waterwheel Park". In the waterwheel park, 12-wheeled giant Lanzhou waterwheel lined up along the Yellow River, playing the "song of years" of the waterwheel "creak and creak". In the garden, the Yellow River rushes, the water wheel rotates, and the canal water winding, which reproduces the harmonious scene of the Yellow River, the water wheel and the agricultural production.
