Dear Sir/Madam,
　　I’m writing to extend my heartfelt thanks to all the nurses and doctors in your hospital.
　　Last month, while I was on a business trip in Taiyuan, Shanxi province, I suffered from a bad cold and a fever, so I was sent to Ward Rom 201, Chaoyang Medical Center. During my stay at hospital, nurses on duty patiently took my temperature, regularly examined my body, and often fed meals to me. In addition, doctors prescribed me the most effective drugs and gave the best medical advice. Thanks to the constant care from the hospital staff, I recovered quickly. Now that I have returned home, the excellent service of your hospital still impresses me. I believe that as patient, I have received the most professional treatment and the most considerate care.
　　Please allow me to convey my sincere greetings toward the doctors and nurses that contribute all their efforts, patience and energy to their patients. Nothing can express my gratitude except my best wishes to them. If you have anything that needs my help, please don’t hesitate to contact me.
