I lived in Hong Kong for 30 years. What was happened in these 3 months did not come out of nowhere. 1997 - now: HK gov allows 150 people from China to immigrate to Hong Kong every day, even there are strong opinion to suspend immigration due to lack of housing and crazy population density problem. Even worse, HK gov does not pose ANY restrictions of the immigrant about their education, language, or criminal background. There was one case that one pro-Beijing arsonist killed 2 immigration Officers but still obtained residency in HK. 2012: HK gov tried to introduce a compulsory brain-washing subject to high school. 500 thousands (out of 7 millions) people protested. 2013: HK gov used crappy reason to turn down a well-known HK businessman to obtain free public broadcast license. So that HK has effectively only one company to run free TV channel. And the news of that channel is highly biased. 2019: HK gov tried to pass extradition law to China. Even after 1 million people protested, HK gov still continues legislation. After 2 millions people protested, the CEO of HK gov only said "the bill is dead" in TV but did not formally withdraw the bill in legislation council. This is only a tiny list of what gov did in the past 22 years. What gov is going to do is to pass a construction that cost trillions of HK dollars (app. 120 billion USD). That will basically empty the treasury of HK, and the future of every HK people. That's why people are so frustrated and protest in that extend.
