What does it mean that the silent flowers in the castle peak are laughing and the silent birds in the running water are singing?

Qingshan is silent, flowers are laughing, and flowing water is silent. Birds are singing, which means that beautiful flowers in the green landscape are smiling slightly, and birds are singing happily in it. According to relevant public information, green means green, and green hills mean green hills. Flowers and birds use metaphors to make the beautiful scenery in mountains and rivers more vivid.
