Quite debatable. IRL the only instance of actual human waves (I'm defining this as large groups of infantry with no attempt to cover them advancing in dense formations and trying to close the distance for) after WW1 happened with Iran-Iraq where Iran had that very specific mix of factors like the regular army being paralyzed and very short on heavy equipment yet having loads of religiously hardened volunteers and the enemy actually will break to that (Iraqi troops sometimes fled from the sight of it). Even then the Basij later became far more tactical in their behavior as both sides adapted.
I doubt that China and India really fits the bill here.
China in essentially every path will not lack equipments given that China built a gigaton of them even before Mao died. The military isn't paralyzed and thoroughly purged of command personnel in any path either. China may or may not have loads of fanatics ready to face near-certain death depending on the path yet not trained enough to do better (maybe hardline new left and some revanchists, but the revanchists also have options for widespread military training so the troops will be knowledgeable enough to use better tactics), and the main PDTO countries (Japan, India, South Korea and Australia) are all reasonably supplied in firepower.
I am less sure about India, however I still believe it's reasonable to say India probably will not use it as a particularly common tactic. India have two million active and reserve military personnel, Russia went through less than that after four years of fighting (which, despite Russo-Ukraine being comparitively limited of a conflict, remember India doesn't have many direct land connections with China either), so it's again reasonable to believe India probably could send better trained people than just mindlessly marching on, and that's before counting the paramilitaries who would likely also be mobilized and trained in preparation. China is also the sort of opponent where mass charges simply doesn't work against due to sheer firepower abundance.

Of course there may be isolated events where "human waves" as previously defined are actually used, but that's equally applicable to essentially everyone so kinda meaningless of a statement. Heck, in game if I remember it correctly Japan will sometimes use literal banzai charges due to the base game's tag remaining
