Sincere thanks to the alumni for donating masks

With the continued spread of COVID-19 infections, supplies such as masks continue to be in short at various medical facilities. Under such circumstances, Professor Gao Xuemei (Department of Orthodontics, School of Stomatology, Peking University), and Dr. Liu Shiying (College of Stomatology, Dalian Medical University), who were enrolled as doctoral students in our department, have kindly donated masks. We express our sincere gratitude for their continued support even after returning to their home country, despite the difficult situation around the world. Warm support from alumni of our department is the greatest encouragement for faculty members and students. We will carefully use the donated medical resources.
