"Scenery" is a metaphor for aboveboard behavior, often referring to "lofty conduct", and later "mountain scenery" is a metaphor for lofty virtue.
The original sentence is from The Book of Songs Xiaoya Chehai, and later Sima Qian's Biography of Historical Records of Confucius was specially quoted to praise Confucius: "There is a cloud in the Book of Songs: the mountain rises and the scenery stops. Although I can't arrive, I am longing for it. " This changed the original meaning.
Original poem: the mountain rises and the scenery stops. Four males and six females are like harps. I got married to comfort my heart.
