There is an old saying in China that a guest has been gone for several years, and the fragrance remains where he has been.

What you said should be "Xun ordered me to stay fragrant for three days." This is to describe Yu Xun, Cao Cao's counselor during the Three Kingdoms period. Because he was a secretary before his death, he was honored as "Xun Lingjun".

Yu Xun has been to other people's homes, and the place where he has been sitting has been smelling for several days. This is a metaphor for handsome men. From Xiangyang Ji: "Xun went to someone else and sat there for three days." Also known as "Xun Xiang".

Go to Baidu and ask Xun Ling. Many poems use this allusion.
