Xiao Jun (simplified Chinese: 萧军; traditional Chinese: 蕭軍; pinyin: Xiāo Jūn, 3 July 1907 – 22 June 1988), born Liu Honglin (劉鴻霖), was a Chinese author and intellectual from Linghai, Liaoning, China. Of Manchu ethnicity, Xiao's most famous work in China is his 1934 novel Village in August (八月的鄉村) which gained both popular and critical praise as anti-Japanese literature. He, along with Xiao Hong, is considered one of the most representative authors of the left-wing Northeast Authors Group (東北作家群). The names Xiao Hong (蕭紅) and Xiao Jun (蕭軍) were chosen by each author so that when put together they would be xiao xiao hongjun (小小紅軍, tiny red army).
In 1925, he entered the Northeast Military Academy (東北陸軍講武堂) which was organized under Zhang Xueliang where he studied law and military affairs. He began writing novels sometime during his studies and in 1929 published the nove Nuo... (懦……/Coward...) which was highly critical of the warlords tearing apart China. He published several more novels, all of which appeared in the Shengjing Times (盛京時報).
In 1932, he left for Harbin, where he began a literary career in earnest. In 1933, he met Xiao Hong with whom he co-authored Bashe (跋涉, An Arduous Journey) and both published for the first time under their Xiao pseudonyms. In 1934, Xiao Jun and Xiao Hong worked together in Qingdao on the supplement to Qingdao Morning Post (青島晨報) and Xiao Jun finished his most well-known work Village in August.
