At April. 2nd, our group had a wonderful time at a Hunan cuisine restaurant“Sparrow” to celebrate the birthday of Prof. Gan. He pointed out that the spirit of the gathering is to enhance the cohesion of our research group, and hoping that we can do this 2-3 times a year. All of us enjoyed delicious dishes and lovely songs from our mates. Wish our lovely professor healthy and rich! Do enjoy great photos taken that night!
