On April 22, 2020, Dean Yuan and Secretary Jiang of the School of Materials Science and Technology came to the doctoral apartment building 2 to visit the doctoral student Wang Yaxiong who stayed on campus during the winter vacation of our research group. The leaders asked Wang Yaxiong about life, study, scientific research, and job hunting, and instructed him to take care of his health, take care of his body during the epidemic, and complete his doctoral studies in good condition. They presented him with condolences on behalf of the college. Thank the college leaders for their concern for our group of students.
