Wizard of Oz. There is a lovely "snail" in the flower border of the Wizard of Oz in Jiang Ecological Park. This is an animal sketch made by Qianjiang Management Office of Hangzhou West Lake Scenic Area using environmental protection materials, which increases the interesting interaction between creatures and plants in the reading glasses. Jiang Ecological Park is located in the east of Hulu Road, north of Fenghuangshan Road and south of Hangzhou Road. Its predecessor was the West Lake silt dredging field. After six years of sun exposure, the seeds of aquatic and terrestrial plants that have been sleeping in the mud of the West Lake for hundreds of years have sprouted, and the river has become a secondary wetland dominated by weeping willows and hygrophytes.
