huaji

Huaji "“滑稽" is a very commonly used emoji that can be found in almost every corner of Chinese internet.

It refers to a "funny" face in which case compared with Japanese people’s impressions of the “funny” emoji, Chinese netizens prefer to use the emoji to tease one another on social media without coming off as overly rude or overbearing.

Five-seveN from Girls' Frontline has two "huaji" pins located on the lower left-side of her official artwork.
