Proverbs that describe one way is unclear and the other is feasible.

From the poem: "When the willow grows dark, the song of high-rise buildings will be transformed." ; "There is no doubt about mountains and rivers, and there is another village." Now I quote the latter section more. In the past, it refers to the scene of colorful flowers, lush trees and flowers, and later it refers to a new good situation that suddenly appears when you find a way out in a corner.
