The poet was moved by the scenery, and he only looked at the moon when he thought about people's difficulties, and sent his feelings with the appearance of the moon. He doesn't feel anything. The feeling of missing overflowed because he saw the coldness and deformity of the new moon, and then linked it with his loneliness and sadness. He couldn't hold back, and he didn't even dare to look at the red beans again. He was afraid that he couldn't help crying out of acacia, and he was extremely sad!
Note: Red beans mean acacia, and Wang Wei has a saying, "When those red berries come in spring, they are a symbol of our love".
