金陵女子大学
From 1920 to 1933, the Bucks made their home in Nanjing, on the campus of the University of Nanking, where they both had teaching positions. She taught English literature at the private, church-run University of Nanking, Ginling College and at the National Central University. In 1920, the Bucks had a daughter, Carol, afflicted with phenylketonuria. In 1921, Buck's mother died of a tropical disease, sprue, and shortly afterward her father moved in. In 1924, they left China for John Buck's year of sabbatical and returned to the United States for a short time, during which Pearl Buck earned her master's degree from Cornell University. In 1925, the Bucks adopted Janice (later surnamed Walsh). That autumn, they returned to China.
