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! 
In March, William and Nigar returned to the group to further study after a long holiday due to COVID-19. On the 28th of March, Williman landed in Guangzhou from Accra, Ghana. In the evening, we had dinner at Donjiang Restaurant. Later, we visited Haixinsha Park in the drizzle. A relaxing night!
