The best ROC era SPG was Anna Chen (陈香梅). She was from a rich diplomat's family and met a Flying Tigers pilot Claire Chennault (that's his name). He was 30 years older than her. Chennault immediately divorced his wife back home and married Anna. Later he became an air force general and supporter of the KMT.
When Claire died in 1958, Anna became the prominent political expert in cold war era US-Asian relations. She influenced negotiations for the Vietnam war and continuing US support for Chiang kaishek's regime. Kissinger even consulted her when he decided to defrost relations with Beijing.
In the 70s she even had a hand in stopping a HK triad leader (Lee Rock's ex colleague in the corrupt police force) from establishing his base in New York Chinatown.
