The reason why Li Bai was demoted was that the poor swallow was leaning on her new makeup. What's wrong with this poem?

1. The poem "Poor Swallow Leaning on New Makeup" means that Zhao, the queen of Emperor Hancheng, is a peerless beauty, but Zhao still relies on new makeup, but what looks like a beauty in front of her eyes does not need makeup, which is natural and amazing. Depress the swallow, raise Yang Fei, borrow the past to compare the present, and realize Yang Guifei's natural beauty.

2. However, due to the use of swallows to set off Yang Guifei in the poem, Gao Lishi, the villain, was induced to make a statement to Yang Fei, saying: Li Bai despised Fei Yang's fat with the thinness of swallows, and fornicated with swallows, causing chaos in the palace. After that, Yang Guifei often spoke ill of Li Bai in front of Emperor Xuanzong of Tang Dynasty, and Emperor Xuanzong gradually began to alienate Li Bai. Finally, Li Bai was forced to resign as an academician and leave Chang 'an.
