Why Bai Juyi is called the Poet Magic?

Bai Juyi's poems in the Tang Dynasty are full of charm, elegant and popular, and even ordinary old ladies can understand them and spread widely. He wrote more than 3, poems in his life, "so that his mouth became sore and his elbow became sore". Excessive reading and writing have reached the point where your mouth is sore and your fingers are shriveled. He writes poetry very hard. Among his poems, there is a poem: "Drunkenness leads to poetry, and sorrow sings to the west in the afternoon." Later generations called it "Poet Magic".
