李商隱 is an immpressive historical person to me.

He was a Chinese and he lived in Tang Dynasty.

He was a poet and he wrote many famous poems.

He was good at using flowery language, but some of his poems are hard to understand.

Because his words are very beautiful, many people like his poetry.

As to his political career, he didn't develop smoothly because of some mistakes. (全文均講其詩，若要提及政治生涯最好也要和詩有關。如仕途不順是否引響其詩作)

李商隱’s poetry is the treasure in Chinese literary history, which makes him an impressive historical person.
