Bro, I actually successfully waged a "guerrilla warfare" against my 教官 (drill sergeant) during my college military training 军训 (required for all college students in China) a little more than 10 years ago. It is not that difficult for a group of dudes who have basic training and cause mass casualties among "occupying troops" caught off guard. So my university and the PAP unit we were sent to gave us the privilege to taste what real combat would be like during the last week of our freshman year military training. We were given type 81 assault rifles with blank rounds, along with the MILES. WE "AMBUSHED AND ANNIHILATED" our drill instructor and his professional troops (revenge for all the rough times he gave us before, such as making us march under the sun for 3 hours wearing those blister-creating green coloured Liberation Shoes解放鞋). During the subsequent "battle," we captured a "fortress" guarded by professional PAP guys. Out team took around 35-40% casualty, but we were judged "victorious" for cutting off "enemies'" supply lines and taking out their frontline outpost. Even the commandant of the base (a senior colonel) suggested that my team should considered careers in the PAP, but I politely declined.
But may be you are right that in a real combat scenario, while each Taiwanese guerrilla group might be able to annihilate many PLA and PAP squads, they may eventually be compelled to lay down their arms once they run out of food and ammo. Still, the amount of casualty they could cause should not be taken lightly, especially since most PLA and PAP soldiers are single child born after 1990 (you are talking about tens and thousands of Chinese families losing their lineages and become completely devastated with no more hopes in humanity). Honestly, the same experience got me interested in IR and political science, but it also led me to detest war and killings in the name of politics. We had a fun "game" with our drill instructors using blank rounds and MILES. but I understand in a real combat scenario, it would mean destroying families and pushing countless wives and mothers to the brinks of suicides. So let's just hope that Xi, Tsai, and Biden can come up something (anything) better than killing people. I'm pretty sure there are solutions to the Taiwan and South China Sea issues beyond lethal projectiles.
