The Swedish Academy in Stockholm on Thursday named Mo Yan winner of the Twenty-Twelve Nobel Prize in Literature.

The academy praised the Chinese writer for what it called his “hallucinatoty realism (魔幻现实主义)”. It noted his ability to combine folk stories, history and modern events in his works.

An academy official said Mister Mo was “overjoyed and sacred” when he learnt he had won the award. He will receive his Nobel diploma, a medal and more than one million dollars at the ceremony in Stockholm in December.

Mo Yan is a leading author of modern Chinese novels. He often writes from memories of his youth. He also sets many of his stories in the area where he was born—Shandong Province in northeastern China.

Mister Mo’s 1987 book Red Sorghum is an example. It is about the extreme violence in rural eastern China during the Communist Revolution in the 1920’s and 1930’s. The story describes the criminal culture of the time, Japan’s occupation and the terrible conditions faced by farm workers. Red Sorghum was later made into a movie.

Mo Yan’s other major works include Big Breasts and Wide Hips, Republic of Wine and Life and Death Are Wearing Me Out.

The Royal Swedish Academy compared him to two 20th century writers: American William Faulkner and Colombia Gabriel Marquez.

Mo Yan’s real name is Guan Moye. Mo Yan means “Don’t speak.” The writer said he chose the name to remember to stop his tongue from getting him in trouble.

China is celebrating the victory of his native son. Minutes after the award was announced, millions of Chinese expressed pleasure and pride for Mo Yan on social media websites.
