Once again I would like to organize this activity on behalf of Miss lovely @seagrove who is still enjoying her holiday. Today is Dragon Boat Festival,  so best wishes to all of you! Enjoy your time home or even at work. This time is a little bit different. In fact, the top ten emuchers who can answer the question would get 1 BB witout any problems because of the festival.
You may also get a certain amount of BBs by expressing your best wishes via the post presented by Miss lovely @shuixian2009 at the following address:
