As the U.S. Army’s first Chinese language student, Joseph Stilwell mastered Mandarin after moving to Beijing in 1920. The next year, he was assigned as chief engineer to construct a Red Cross famine-relief road in Shanxi Province. During World War II, Stilwell was the U.S. commanding general of the China-Burma-India Theater and Generalissimo Chiang Kai-shek’s chief of staff. Guan Wenchun, his Chinese language tutor, also taught Stilwell’s children, who thought of him as a grandfather.
