What do you mean, "if you can see the sun, although it is brilliant, why are you depressed at dusk?"

"But when you see the sun, although it is brilliant, why are you depressed at dusk?" Zhu Ziqing explained himself like this. "These two poems just want to be positive and optimistic in reality and persevere."

In his later years, Zhu Ziqing pressed a note under the glass plate of the bookcase, which read: "But if you can see the sun, although it is brilliant, why are you depressed at dusk?" He used two poems written by Li Shangyin in the Tang Dynasty: "The sunset is infinitely beautiful and is buried by the coming night".
