Professor Feng Zhang's final lecture and retirement party

On March 25, Professor Feng Zhang's final lecture and retirement party was held. The title of the lecture was "長江後浪推前浪　江山代有人才出" which is meant to encourage our younger generation. The lecture was not only about his research, but also about his life, and we could fully feel the personality of Professor Zhang.
Thank you very much for your always kind and also sometimes kind!
