Four years in UIC is one of the most simple and joyful time for me, and this time also provides me with an opportunity to shape myself. The deepest feeling during this period is that all the professors and teachers impart their knowledge and skills to us, which helps us to form our own views. Also, we students can learn a lot form group brainstorming and make up for weak points of ourselves from others. PRA is a wonderful existence for me. It is because I have gained a lot of unexpected opportunities in PRA and made myself closer to the one I want to be. So I hope that my younger brother and younger sister can enjoy this happy land and experience an interesting life here, too.
