What does it mean to build a stone down the mountain?

The Stone under the Mountain is a poem from Bai Juyi's Farewell to Ancient Grass in the Tang Dynasty. This poem depicts the scene of parting. The poet stood on the ancient grassland and looked at the distant peaks. He couldn't help feeling the sadness of parting. In the poet's pen, hills and stones have become symbols of sadness, symbolizing the separation and strength of life.

Besides the artistic conception in poetry, there is other meaning on the mountain. In ancient wars, rocks were key military resources and played a decisive role in many battles. Because roadblocks on the mountain can be used to build fortifications, while stones can be used to make weapons and build walls. Therefore, "the stone under the mountain" can also be interpreted as the need to pay attention to the use of its own resources.

In modern society, with the development of science and technology and the rapid development of economy, it seems that we no longer need to pay attention to traditional resources such as rocks. But in fact, there are many "mountains" and "stones" in modern society, such as environmental resources, natural resources, human resources and so on. The protection and utilization of these resources still need our continuous efforts and exploration. Only in this way can our society be more lasting and prosperous. Therefore, the meaning of "the stone under the mountain" still has continuous vitality in contemporary society.
