I’m going to leave France and return to China tomorrow. I have spent a fantastic 6-month in France. It has been one of the most valuable experiences in my life. I would like to thank INRIA Nancy for hosting me. It is really nice for me to join ALICE team and talk to all you guys. I also want to thank all my friends over the world who provided all kinds of help to make my life in France much easier and happier. I hope I can meet all of you in the future.
