Happy mid-autumn festival to you!
Mid-Autumn Festival (or 中秋节 in Chinese) is a day where everyone eats moon cake. Plain and simple.
Moon cake consisting of different flavors such as egg, meat, bean paste and vegetable filling are passed around and exchanged like chocolate on Valentines Day. My heart-less, unmerciful, despicable company gave us a 100 rmb voucher for 85 degrees (famous Shanghai bakery chain) moon cake set (which was probably charged to us in tax or something, those bastards!)
