All civil servants in Hong Kong has to take a Chinese Communist Party style of loyalty oath and it seems this will be also required of forging teachers at public schools and later on this will be expanded to all teachers in Hong Kong so that they will not be teaching students historical facts and talk about democracy.
This oath taking will also lead to that corruption in Hong Kong will increase to similar levels as in PRC as if you report someone higher up for corruption, this one will simply say you broke the oath and suddenly you are the big criminal, so how many will be then prepared to report corruption when they will be prosecuted for breaking the oath that the CCP will see was the most major crime, most people will just turn the blind eye to the corruption and suddenly Hong Kong will be ruled by extreme wealthy criminals.
Don’t forget that a oath taken under threat (those who don’t take the oath will be fired) is not an oath that you are ethically bound to, so please keep on fighting for freedom for Hong Kong.
