2, 4, 6, 8 we don't wanna integrate....
Since your prophet is getting boring, let's discuss the logistical reality of this coming World War.
Firstly, China has not called for a general mobilization nor called up the reserves. It would take more than a month to call up, equip and move all those forces. This would be noticed in China. The Russians and USA and Taiwan and Japan watch China very carefully. There are no less than a dozen spy satellites synchronized over their major military installments/locations. There is nothing like this going on.
And be assured, they'd need that ground army. Their real numbers are impressive, but they have to call up 800,000 reserves to get to three mil. Taiwan, Thailand, Viet Nam and Myanmar can match that three million total, plus have a combined navy that is stronger, because India would not sit still.
Once again, the facts will counter your speculation. Thailand, Taiwan, Malaysia, Myanmar, Viet Nam, Pakistan, India, Japan, Singapore, Bangladesh and even with low numbers in each country, pretty soon you come up with sufficient numerical strength to hold the Chinese army, navy and air force at bay if they were to decide on, let's say, Continental Asian hegemony in the next 41 days. (And remember, they have a 3 million man army - not 200 million. How many could they commit to crossing into Southeast Asia, where there are more than 3 million forces to oppose them.) They will/would be bogged down before they got near Indonesia, The Philippines or Australia, believe me.
And that assumes that their traditional worry - the big bear to the north - does not take advantage of this situation. Russia still has the same or a little fewer nuclear weapons as the USA. China launches one nuke at Manila and your eight hours of earthquakes will be a lot more like two hours of the four horsemen. Nukes would rain down on China from all directions. China cannot get to the Russian silos - doesn't have the missiles. They do not have the fleet or the technology to stop the missiles from Russian subs, either.
They'd have ONE ally, North Korea. But there are no targets near North Korea other than South Korea. (Arguably, they could point towards Russia or Japan, but the minute they did so, the South Korean and American forces would cross the border en masse and reduce Pyongyang to rubble. So North Korea might try to take advantage of the opening to invade the South, but they're not going to be available to help China out.
And, in this scenario with China surely loosing, I've left out massive American or European intervention - just keeping it local to the Asians.
So,... No! Your war's not going to happen and if it was to, The Philippines would be an afterthought to China. China knows history. They well remember the last Asian power set on regional domination who decided to start with an attack on the islands.
