But she grew up in Shanghai and the U.S., I doubt she could speak Hainanese

Her father’s surname was Han and he changed to Soong. Her mother is Shanghainese. She could only speak Shanghai dialect and English, she doesn’t speak Mandarin and Hainanese.

I surmised that she should be able to speak Mandarin as Mrs Sun Yat Sen and also being much respected in the PRC.
