& lt& lt Vegetation > > The moral of Bai Juyi's poem is quicksand and urgency.

Grass and Trees is a group of poems that praise things and express ambitions. Through personification, the author enthusiastically praised the aloof poplar, tenacious cactus and refined plum blossom. At the same time, he used vines and toadstools as metaphors, sharply criticized parasitic and ulterior climbing phenomena, and wrapped himself in a beautiful coat to poison human quotations. The whole set of poems constitutes a sincere and warm tone. In its background, the poet's strong heart of good and evil and persistent pursuit of upright personality are quite distinct. It is this that gives this group of poems touching power. It is not only the poet's frank description of the world, but also his sincere confession of how to face the world, as implied by Bai Juyi's poems quoted in the Poem Inscription.
