Re: "fist fights"
Don't forget that they dammed several rivers, waited for Indian troops to enter the river bed, then unleashed a torrent to drown them. While they were fighting for their lives, they attacked the with nail-encrusted bats, Those they didn't bludgeon to death were pushed off the side of mountains to plummet to their deaths instead.
This wasn't a border skirmish. This was a pre-meditated Chinese government mass murder.
