I am Meng Xiangyu, a young man from China. Now, I am working in the Center for Evidence-based and Translational Medicine of Wuhan University. Almost a year ago, thanks to professor Teshima's kind acceptance, as a visit-student, I had been lucky for having the chance to spend two months studying in the Department of Hematology of Hokkaido University Hospital, a place that offered me a lot of beautiful memories, where I learned a lot from these kind, skilled and erudite doctors. These doctors, devoted to providing best medical care for their patients, always consider satisfying the patients' needs as the most important task to address. They have been sacrificing a lot of their out-duty free time to do researches and to learn from current optimal medical evidence, serving a common goal of helping patients and improving care quality. Being young and energetic, always modest and hard-working; being senior and experienced, still always modest and hard-working. They are respectable fighters against hematological diseases. I am grateful for having been with them, and having studied and worked with them. And this abroad-study experience, as a precious page of my life-diary, is everlasting there in my heart.
