Painting Han benefits Wei and changing Feng Shui.

The reasons for introducing Han to benefit Wei are: the climate in Guanzhong and northern Shaanxi is dry and water resources are tight; With the rapid economic development in these areas in recent years, the demand for water resources is increasing day by day, and the local water resources alone can no longer meet the needs of industrial and agricultural production and people's lives; Overexploitation of groundwater will cause a series of serious consequences.

Disadvantages: the process of introducing Han into Wei needs to cross the Qinling Mountains and build tunnels, which will cost a lot of money; It may destroy the ecological environment of Qinling mountains, cause landslides and mudslides, and endanger biodiversity; The geological structure of Qinling Mountains is complex, so it is very difficult to build tunnels. There is also the issue of resettlement;

Significance to the water receiving area: returning to the problem of insufficient water resources in Guanzhong area will promote the complexity of industrial and agricultural production; Conducive to the protection of the ecological environment in Guanzhong area; It can also supply water to northern Shaanxi to promote the development of energy industry in northern Shaanxi;
