Are the blue mountains and white waterlines in the north and east of the Great Wall talking about wetlands?

No. There is a blue mountain line to the north and east of the Great Wall. Poems with white curves of water mainly describe green hills, white water and city walls. Strictly speaking, they are not wetlands. However, there is a certain wetland ecological environment in Baishui River basin and its surrounding streams and floodplain wetlands, which has certain wetland characteristics. These wetland areas have high biodiversity and ecosystem functions, and can provide important ecological services for local social and economic development.
