I am a master candidate in the school of computer science and technology, Fudan University, Shanghai, China. Every year, there are exchange programs between Karolinska Institutet and Fudan University. The program is about medical informatics. I was very interested in medical informatics, so I applied the program. Moreover, I have stayed in Shanghai for 6 years, I thought I should have a change and experience something different. Experiencing different culture and learning some advanced technology would be fascinating to me. Although I knew the study aboard-information very early, but the selection for the exchange study was quite late. It was in the middle of the Spring semester, that gave us something inconvenient. I was lucky that vaccinated or bring certain certificates was not required for me.
