A vlog about Hong Kong protests filmed by a Canadian tourist Toby Guu became a smash hit on the internet. Guu's video shows a man being beaten up by radical protesters in Hong Kong Sha Tin Mall on September 22. Mobs attacked the man non-stop while being treated by EMTs. But after that, Guu received a lot of threats from the rioters. CGTN has an exclusive interview with Toby Guu.
