Her first husband, Chinese diplomat Clarence Kuangson Young, was assassinated by Japanese imperial forces during World War II. She became the long-term mistress for the diplomat and politician V.K. Wellington Koo, long before her husband's death. After the war, she moved to the United States; in 1956 Koo divorced his wife and married her."
