The "best" answer is not appropriate.
(1) it says "Acacia" misspelled love, should be to write a poem of missing. As far as missing is concerned, it may be love, affection and friendship, but when it comes to Wang Wei's Acacia, it has nothing to do with love. Judging from another name of this poem, A Gift from the River to Li Guinian, that is to say, this poem is for Li Guinian, so it should be written about friendship and farewell to friends. It seems that Li Guinian's circle of friends is very strong. Du Fu (see Encountering the River) and Wang Wei both sent him poems. Li Longji asked him for songs and asked Li Bai to write lyrics for him.
It is also inappropriate to say that Zhuliguan is a lyric poem of praise. It should be written in a quiet and peaceful way with a touch of joy.
