The Taiwanese have installed pipes underwater to flood those beaches with gasoline, amongst other things. They are quite ready to humiliate the PLA.
The PLA will also need to send a large contingent of counselors as the PLA soldiers get very upset when kept in the field for a week.
A former PLA general published an article in one of their mouthpiece publications. He said that in the event of a war the CCP would perform a massive decapitation strike on all US bases and possibly cities. Forget that it might lead to complete annihilation of the Chinese. Putin has proven that reality need not play a part in the decision process. Xi, like Putin, has created an atmosphere where no one gives him bad news. This is a characteristic of autocratic regimes. The Japanese ran a war game for the battle of Midway, which they lost. The Junor officers had positioned the American fleet almost exactly where it ended up in reality at the start of the battle. They were humiliated because that wasn’t the way the Americans would play it, so they did it again where the Japanese won. So, you can’t count on reality being a factor.
