maybe its cold out, the boy is wearing pants and as science tells us girls get cold faster than boys. They're also wearing long sleeves and their complexions have lightened. This is clearly the winter 1997 edition of this textbook.
I wonder if Mr China Watcher would be just as mad if they gave the boys shorts and short sleeves in the new version? Xi is feminizing the men? Chinese children so hungry they lack body fat to stay warm even during exercise?
idk, if you're going for a run, doing it in pants seems easier and more comfortable than a skirt. never worn a skirt in public yet though so i guess i got to get back to you on that. maybe some other hexbear user can chime in with personal experience on running in both
Skorts (skirts with shorts underneath) are just as easy to run in as shorts or pants, in my experience, because they'll usually have pockets or stitching to keep the skirt part in place. Skirts suck for active wear imo, cuz they usually flap up against your torso when you run if they're short, or tangle around your legs when longer. Can't speak for old timey kilts and whatnot. Pants with pockets will always be my go to. I fully support skirts as fashion wear for everyone though.
