It is my first week to be an MBA in Tsinghua University. What impressed me most during the past several days is the wonderful work done by MBA office. They are always keeping us updated, sharing all information with us. I am surrounded by so much information, so many new friends, so many resources and activities. My classmates are open-minded and warm hearted. It is time to learn; it is time to set up the network; it is time to choose.
