This clip is a great clip to show the world that not ALL of Hong Kong is in support of the demonstrators as the MSM is trying to tell the world. I've seen plenty of Videos where normal citizens standing up to the mob at grest risk to themselves!
The principle in the clip must be praised for his bravery. I'm sure he will be targeted by the mob!
For those of you who can't understand cantonese. He basically told the students to respect the national anthem, and the flag. And that they must stand up during the national anthem! He also mentioned about respect during the colonial days.
But most importantly, he said if they don't show respect, then they have choosen the WRONG university!
My hat off to you, sir!
It is important to note this clip is from 2017.
It is also important to note that the headmaster told the students that the school had always flown the Chinese flag, it is non-negotiable, this was done even during the colonial era despite colonial oppression taking away school funding and real estate.
