I think the closest comparison to China’s military would be that of the Kingdom of Saudi Arabia. Money is no object for either force, so there are lots of shiny new toys, but little for training — especially the realistic kind.
Saudi Arabia can’t do much other than bomb rebels in neighboring Yemen. Their army is not competent to to much else.
China’s army does look spiffy on the parade ground, however.
The one constant with Chinese military tactics is the total disregard for casualties. No matter how difficult the operation, the human cost has always been a small matter to them historically. Add in the communist disregard for human life, and you have a scenario for miscalculation that could be disastrous for life as we know it. Trump is the only leader in the west that has shown enough gumption to possibly forestall PRC aggression. His re-election is essential.
