This 20-year old girl from Hong Kong, now living in the UK, is being threatened by Chinese authorities, and treated like Public Enemy #1 because she promoted democracy there when she was a young teenager.
Chinese officials consider her -- get this -- a "threat to national security", and have vowed to "pursue her for life", even offering a sizable bounty for her arrest or capture.
The Chinese authorities have cracked down severely on dissent in Hong Kong since some human rights groups dared to protest against their heavy-handed suppression of human rights there, and no one feels safe anymore even if they leave the country.
