On June 27th, there was again the birthday party for Prof. Xiaohui Zhang, Prof. Xiayu Xu, and Guoxu Zhao. As the party came at a time when the World Cup is kicking off, Mrs Liu brought us gourmet football cake. We sang the birthday song and eatting the cake together. After that, things became crazy. "Have a food or cake fight!" Soon everybody's face was wiped on colorful cream, like The Smurfs. Last weekend of every month, BEBC will held such a birthday party for the birthmen and celebrate it together.
