Through 2034, if PRC invades and Taiwan and the US's major military forces on the island are gone, i.e. no tanks and no planes remain in Taiwanese control or are operating from the island in defense, will there nevertheless still be significant guerilla resistance?
Examples from most typical to least, after a Chinese invasion
1000 armed Taiwanese military special forces units hide in the hills, raiding PRC controlled cities and attacking troops <=== very typical, clear YES
100 armed Taiwan civilians+ex military men hide in the hills, not surrendering, but not doing much, but still shooting/raiding/killing soldiers sometimes <=== still counts as YES
100 possibly separate civilian individuals organizing via anonymous message boards, sending suicide drone strikes against PRC targets <=== new pattern of resistance, and still counts as YES
^^^ above this counts
*** Below this doesn't count
Students allegedly distribute anti-PRC media and sometimes perform anonymous grafitti or symbolic acts of resistance
Taiwanese gangs allegedly operate a black market in cities which unclear political affiliation or other mafia activities
Individual anonymous Taiwanese people allegedly sometimes resist control or rule, possibly with violence or intentional mistakes
So overall, violence+organization+resistance pushes you up; lack of those push you down. The examples above are not exhaustive. At evaluation time we will attempt to figure out the reality of what's going on, and then slot it in to the spectrum above.
It's likely that it will be hard to know what's actually happening, due to propaganda. In a case like that, I will attempt to determine the truth, evaluating any possible source, and resolve based on what I think the truth is. Information included would be broad, combining statements from the West and the PRC. I.e. if there are western statements suggesting there is resistance, but PRC silence, and independent international satellite data suggesting continuing violence and explosions, that leads towards YES. But things which can be dismissed as potentially purely western propaganda with weak supporting evidence may not be enough to resolve YES (unnamed sources, doubt, PRC denials, missing evidence). I will prefer to wait to find out what's happening than resolve early.
To qualify:
there must have been an invasion
it must be within a year of the invasion being "successful" i..e after official surrender or nearly complete conventional military control
the resistance must last at least a month.
And, to resolve true, this must complete before the end of 2034.
