Restaurant patrons in Qingdao can now judge an establishment's sanitation level from a smiley face!
-A green "smiley face" indicates that the establishment follows excellent sanitation standards.
-A yellow "neutral face" indicates average sanitation standards.
-A red "frown face" indicates a lack of sanitation standards.

**Restaurants that receive neutral and frown faces will be given a timeframe in which to improve their sanitation levels.
