Origin: This allusion comes from Li Longji's praise of Yang Yuhuan.

Quote: Yang Guifei is naive and indulgent, and has no great political ambition. She is young and beautiful, and has a certain talent. She likes dancing with Emperor Xuanzong of the Tang Dynasty. She is like-minded and considerate. But A's honey is B's arsenic. She can understand Xuanzong language, but she can't understand people's livelihood. Her nobles cling to the dragon and run amok, her "adopted son" deceives his superiors and deludes his subordinates to launch a coup, and her lover is addicted to debauchery and disregards state affairs. In the end, the world was in chaos, and the Anshi rebellion, this deductive flower finally ended in Maweipo.

Quotation: "Honey of A is Arsenic of B" —— Datura by Yi Shu

Interpretation: Women are like Datura flowers, beautiful but poisonous. When you are attracted to her, you can't help approaching her. The closer you get to her, the more confused you are. In the end, like an unconscious bug, it can only fall from the beautiful flowers and plants of Datura and die.
