"Worried about the bright moon, go to Yelangxi with you" is a heartfelt encouragement and relief to the poets. It means that I send my feelings for you to the bright moon, and I hope that the bright moon will follow you with my thoughts until you are in a distant place, chatting and comforting your lonely figure. In Li Bai's pen, the bright moon is an elegant and pure sentient being. In this poem, I gave my "sorrow" to the bright moon, which not only showed that Li Bai and Wang Changling were as pure and bright as the bright moon, but also implied that their friendship would last as long as the bright moon existed. It is enough to have a bosom friend in life, not to mention Wang Changling has many bosom friends!
