The larger point is that it'd be way too messy for them to even try. Basically on the scale of US/SK invading NK.
Besides that significant causalities and economic damage to both sides, which of course they'd eventually win, but it'd be a geopolitical disaster that won't end with the quelling of the armed forces.
I’d imagine China would more likely begin blockading Taiwan, at least until the US and the west responded. Given the strength of US naval power it’ll be a while before China consider even that.

China has far more to gain not going this route.
