This idiom originated in ancient China. It describes a very remote and backward place, as if surrounded by earth mountains, with no development prospects. This idiom can be used to describe some poor and backward places, or someone's situation is more difficult. But we should know that this idiom only describes a situation and does not mean to belittle anyone or anywhere.

In modern society, many people are still in a state of mountains and rivers, and their living standards and development opportunities are relatively low. For example, some residents in remote areas and some low-income family members may have a much lower living standard than ordinary residents in cities. We should pay attention to the survival of these people, improve their living standards and development opportunities, and let them have a better life.

In the new era, we should strive to eliminate the situation of the earth and mountains in all directions, break the state of poverty, backwardness and isolation, and let everyone enjoy the opportunity of development and progress. We should strengthen infrastructure construction, develop economy and education, improve people's living standards and make our own contribution to the long-term stability of the whole country.
