One of my friend told me why the boring cute look is more popular in China and I find it very true, she said " asian guys are more shy and timid in GENERAL, therefore a hot, edgy, and sexy girl is too much for their taste, and those cute/ the girl next door type seems more approachable, and suitable to them"
Also magority of the chinese street girls has small eyes, tanned skin, flat nose, therefore people wants to see some more big eye roound face baby doll type of girls in media.
In china 80% of the population dosen't care about fashion, the 19% of them who cares about how they look just try to look cute because of the influence of chinese media. Only less than 1% know/at leasat care about what is true high fashion; to them high fashion is LaLa land.
I am 100% chinese BTW
