Whose work is "A bouquet of dark flowers, ten households are blessed"?

Bai Juyi wrote ten poems "Qin Zhongyin" in Chang 'an, and this poem is the tenth. The first four sentences of the poem are about watching the excitement of peony; Four sentences Peony is expensive; Thirdly, write six sentences about the transplant protection and charm of peony; The last six sentences describe a farmer's feelings after seeing peony. The whole poem reflects the extravagant and decadent life of the exploiting class with popular language, simple narration and descriptions of bureaucrats and nobles who spent a lot of money on peony. "A bunch of dark flowers and ten households" equates "a bunch of flowers" with "ten households", which reveals the fact that the dignitaries in feudal society squandered the people's hard work and indulged in excesses.
