Why are the banks of Ning River and Ji Canal not green?

For a long time, due to the winding of the Jiyun Canal, the small cross section of the main channel, the weak embankment, the sinking of the embankment, the lack of elevation, and many dangerous sections,

The greening of Ninghe River can start from the Jiyun Canal. The proposal is divided into three paragraphs. Lutai Section, Ninghe Town Section, Fengtai Return Section, etc. will be gradually extended when there is money. Qilihai can build a greenway around the sea and run and ride.
