I'm not sure why protestors would take tips from the HK protestors. After all, they were not at all successful.
I attribute this problem to two things:
1) Hong Kongers are culturally mostly British.
2) Modern British culture has no martial tradition whatsoever, and therefore no practical ability to mount a successful resistance to any kind of even moderately-equipped state actor that is willing to use force.
If you're dealing with a polite government that's strictly constrained by voter approval, then the HK strategy might work.
