Li He (A.D. 790-8 16), a native of Fuchang (now Yiyang, Henan) in the Tang Dynasty, left behind eternal famous sayings such as "Dark clouds crush the city to destroy it", "The cock crows all over the world" and "If there is love in the sky, it will be old". At the age of 20, Li He went to the capital Chang 'an to take the Jinshi exam. Because my father's name is Jin Su, which sounds the same as Jinshi, I was disqualified for offending my father's name. Later, because of his high literary fame, he served as a humble little official of Feng Lilang and stayed in Beijing. Li He was ambitious and arrogant, but now he has become such a small official like a servant. He felt humiliated, so he resigned from his official position and returned to his hometown in Fuchang to live in seclusion. Li He often rides a lame donkey and carries a worn-out toolkit to go out for inspiration. His poems are full of imagination, and he often uses myths and legends to convey his feelings, so later generations often call him a "ghost genius" and his poems are "the words of a ghost fairy".
