I agree that this is tasteless and rude, but I will say that after seeing the lowest ranked ones it seems they're ugly on purpose. Kind of like a Chinese version of western women dying their hair bright blue, shaving half of their head, and getting a bunch of hideous tattoos. Calling them ugly is just stating a fact.

In the video, all of the lowest ranked girls, with almost no exceptions, looked like men. They wore masculine clothes and cut their hair in what I can best describe as "hobo who wants to look semi-presentable for the welfare office chic". They also clearly never bathed. I'm guessing China has a similar problem as the west where ugliness and disgustingness is being celebrated as good and the artist was trying to make a point.

Or he's just a coomer and the point was made accidentally. Either way.
