I am a friend of Professor Dong Yi. First of all, welcome to Chengdu for your trip. I am planning to take you to visit the Ultrasound Department of West China Hospital on Thursday morning. However, due to my work schedule next week, I am unable to personally accompany you. I have arranged for Dr. Qiu Tingting, an assistant professor in our department, to receive you.
