What style does Li Shangyin's poems reflect?

Li Shangyin was born in an official family, but his family was poor. He lost his father at the age of nine and studied with his uncle in his early years. In the third year of Emperor Wenzong Daiwa (829), he was hired by the army to make Hu Chu work hard. At the same time, he began to show the poet's unique sentimentality and Leng Yan style in his poetry creation.
