> very few Chinese natives like the emojis offered by western countries (and I guess vice versa)

As a Westerner, the Tencent smileys are mostly better. On QQ they animate, which I don't like, but on Wechat they're static and they provide much better options than the Western set. I don't think there's ever been a good "looking skeptical" smiley anywhere, though.

For some reason, Tencent semi-recently redid all their smileys in a much uglier style. I wish that hadn't happened.
