葛蘭 Ge Lan (also known Grace Chang) - 教我如何不想她 “Teach me how not to miss her” (originally a poem by Luo Zhihai)
This video (1962) is a great example of global music flows! (wait for it) Ge Lan was born in Nanjing and trained in classical Beijing Opera, and later moved to Hong Kong and began starring in movies. Port cities are natural circulation points, and many of the record labels of 30s Shanghai also moved to Hong Kong with the rise of the CCP.
