This sentence comes from [Qing Dynasty] Chen Danran's "Yuanyan's Second Move to the Capital and Establishment of a Fan", which means: You must have a long-term perspective when looking at problems. If you cannot consider long-term interests, you will definitely not be able to make short-term plans. You must also look at problems comprehensively. If you cannot think about the problem from the overall perspective, you will not achieve success in small aspects.
Those who cannot see the overall situation and plan affairs do not have the wisdom to seek (govern) a region; those who cannot consider problems from the perspective of long-term interests cannot plan the immediate affairs well. It means taking a long-term view and should not just focus on the immediate gains. It’s about looking at the overall situation and being aware of the overall situation.
This is the strategic saying of Chen Danran (1860-1930), a scholar in the late Qing Dynasty. In the face of the aggression of foreign powers and the decline of the Qing Dynasty's power, Chen Danran wrote "Proposals for Moving the Capital and Establishing a Fan" in the Wuxu Year of Guangxu (1898), proposing this famous point of view.
