I wonder what motivated Chinese students to offend the poor guy from Hong Kong. I can think of several plausible reasons: - pure fanaticism of CCP China - such bullying is just the norm in daily lives where they grew up - someone from Chinese special services approached them and their families and pressured them to make such comments (to peer pressure)

Knowing that they made to the USA makes me believe that the first one is improbable and the last reason is so convincing.
