There's an important political figure in the history of modern China: https://en.wikipedia.org/wiki/Sun_Yat-sen
He studied medicine in HK. He lived in Hawaii for a time [1]. He had a political philosophy: https://en.wikipedia.org/wiki/Three_Principles_of_the_People
To my surprise I found Sun Yat-sen is still revered in China. He was Cantonese, like many of HK people. He has a University in GZ named after him!
If you would like to learn more about history of China this professor is fantastic: https://en.wikipedia.org/wiki/Richard_Baum, in particular, The Fall and Rise of China The Teaching Company, 2010 is really good. It's on audible.
