So the exact wording of the "security law" that China forced onto HK was revealed only after it passed. It includes this: outlawing four national security crimes: subversion, secession, terrorism and colluding with foreign forces. Now HK schools are being told to remove books that breach those 4 rules: https://news.slashdot.org/story/20/07/06/181226/hong-kong-government-tells-schools-to-remove-books-breaching-security-law.
#FreeHK now, before it's too late.
@chebra it's too late already. There was never any will to free hk. It was meant to come back to china anyway... but one can wonder why is china in such a hurry to hit at hk freedom, or why can't china accept one exception to prove their point.
I personnally believe they are prisoners of their own propaganda. Somehow they have lost control of the machine and it now only follows the most zealous politicians.
