Let's play a game: Rating Hua Cheng's smile

This game is inspired by Guoshi Mei Nianqing, who said that Hua Cheng had a fake smile.

So, we will be rating Hua Cheng according to the sincerity of his expression, preferably a smile.

Rules are simple. Comment a picture of Hua Cheng (include your rating if you want), and rate other people's picture according to how sincere he looks like. You don't have to rate every picture you see.

Rating example: 10/10

Any type of media is fine, donghua, manhua, illustrations, fanart (please credit the source, esp if its fanart, same rules apply even if you are the artist).

Have fun!
