On June 2-4, Shizhen, Jianchu, Jun and Gan attended the 5th Microplastic symposium held in Wuhan. Wu Chengxi (吴辰熙）who was a CUG-Wuhan PhD student worked with Professor Qi Shihua host the symposium. Both Jianchu and Gan gave talks, which came out to attract a lot of audience. In particular, Jianchu was surrounded by many girl students after his talk. We had time to meet many friends from the CUG-Wuhan for the dinner, after which, we, guided by Hairong, walked along the Yangtze River in the evening neon lights. Shizhen was exited to meet so many colleagues working in the area of microplastics. A nice meeting!
