Following the death of her husband, Lin, Yen was left nearly destitute. Her family had lost all of their money and possessions during the war, and Yen was forced to find a way to support herself and their two children.
Yen quickly enrolled at Columbia University, graduating with a Masters in Public Health in 1949. Two years later, she finally found a position—as the senior staff physician at Battey State Hospital in Rome, Georgia. After several years, Yen became a physician and clinician at the Georgia State Tuberculosis Hospital—a position she maintained until her retirement in 1967.
Yen Hui Ching lived in retirement for twenty years before passing away on June 25th, 1987.
