I know about this guy’s background briefly as he grew up from those schools with solid Communist culture, that’s why he is very supportive with the HK national security and central authority. He is not happy with the British Govt back in the day when they were in charge. And I also learned that he is not supportive with people who think Taiwan should be on their own instead of being part of Mainland. I like him teaching thru internet but he should take some time to think about what diversity of people is. Don’t be too antagonistic toward our used-to-have HK culture.
