Kong Anguo, courtesy name Ziguo (子國), Kong Anguo was a Chinese classicist, philosopher, and politician of the Western Han dynasty of ancient China. A descendant of Confucius, he wrote the Shangshu Kongshi Zhuan, a compilation and commentary of the "Old Text" Shangshu. His work was lost, but a debated fourth-century forgery was officially recognized as a Confucian classic for over a millennium.
