Appreciation of ancient poems:
There are no people in the empty mountain, so first describe the empty mountain from the front. Wang Wei particularly liked to use the word "empty mountain", but in different poems, the realm it expresses is different. "After the new rain in the empty mountains, the weather is late and autumn comes" ("Mountain Dwelling in the Dark Autumn"), which focuses on expressing the clearness and cleanliness of the autumn mountains after the rain; "People are idle and the osmanthus flowers fall, and the night is quiet in the spring sky" ("Birds in the Stream").
It focuses on expressing the tranquility and beauty of the spring mountain at night; while "empty mountain without people" focuses on expressing the emptiness and tranquility of the mountain. Because there are no human traces, this mountain, which is not empty, seems empty and void to the poet's feeling, just like an ancient state. "No people in sight" concretizes the meaning of "empty mountain".
