In the early years of Qianlong, the increase of gardens in Haidian area in the western suburbs of Beijing directly affected water transport.

In the early years of Qianlong, there were many gardens in Haidian, a western suburb of Beijing, and a large amount of garden water made Beijing's water consumption increase day by day. At that time, most of the garden water came from the water flowing into the West Lake from Yuquan Mountain, which was also the water source of Tonghui River since the Ming Dynasty. If a large number of Yuquan landscapes are intercepted, it will threaten the water level of Tonghui River from Beijing to Tongzhou and directly affect water transportation.
