The OTL Chinese intervention did not end in their complete and utter victory, but a stalemate in which both sides judged the cost of attacking was too high to be worth it. I don't see why this one should differ, just with the stalemate happenening while still near the Korean border.
The US in the OTL Korean War was forced to hastily withdraw back to the 38th parallel because the Chinese intervention had suprised them utterly unprepared. Ironically part of that unpreparedness had to do with the bitterly cold Korean winter conditions. Not the first time that happened to someone when fighting communists, I'm told. Ahem, coming back to the point: the OTL Chinese advance into Korea was not based on some memetical 'you'll run out of bullets before we'll run out of conscripts' scheme. Such tactics have no place on a modern battlefield.
Notably, in this timeline the Koreans are the opposite of surprised. They had more than a year to prepare for a confrontation they perfectly well knew was coming. Presumably Korea and its allies will have air superiority. The Chinese are pushing their armies into a heavily fortified meat grinder.
