Luo Yin (c. 833 – 26 January 910, courtesy nameZhaojian), born Luo Heng, was a poet of the late Tang dynasty and early Wuyue kingdom. Luo's poetry was widely read and cherished, but he was unsuccessful in life; having failed the imperial examination 10 times, he had been penniless until the warlord and Wuyue founder Qian Liu gave him official posts in his hometown Hang Prefecture. Luo was said to be very ugly and arrogant.
Luo was born in Fuyang, Zhejiang. At the age of 20, he took his first Imperial examination. He failed the exam ten times. As a result, he gave himself the pseudonym "Yin" (lit. "dormant").
He was said to be of ugly countenance, and that he thought highly of himself and looked down on others. A famous anecdote demonstrates his ugliness: grand councilorZheng Tian had a young daughter who enjoyed literature, and Luo Yin's poems which she frequently read out loud were her favorite readings. Zheng Tian became worried about her infatuation. One day, he invited Luo to his residence, and his daughter took a peek at the guest from behind the curtains. From that day on she never read his poems again.
In 870, he was given a post in Hunan. However, he was unable to take advantage of the post, and returned to Zhejiang in 887. Penniless and frustrated, he later became an assistant to Qian Liu, but never shed his arrogant ways. He died at the age of 77.
