It's been 6 weeks since my last update, asking the same question [here].
The tension here has grown even further, and now we have received hundreds of Hong Kong citizens being detained while crossing the boarder, not only academics from the HKU, but also staff from the UK Embassy (It might sounds unreal, but Google "Free Simon Cheng" for yourself to make sure it's not fake news).
I have a firm reason to believe that I am risking my own life if I travel to mainland for ICPC in the contest season (Oct~Dec). ( Again, it is not the first time that the HKU programming team is rejected by the Chinese authorities hence deined from ICPC contests. )
My chances of participating ICPC is getting slimmer as we get closer to the Chinese National Day on 1 Oct. What could I do to protect myself?
