Oh dear! The first time I entered my alma mater as a tourist. I haven't been there for a year and a half since I came back from my alma mater. This time I accompanied my friend to see his UCB (University of California, Berkeley) and had time to go back to his alma mater. Visiting teachers and classmates, I saw Professor Tao Zhexuan. Out of courtesy, no photograph was taken. ~ The general visitors in the library can't get in, and I don't have a card when I go out in a hurry. However, hey hey, you can get in with the ID number of the school at that time. How beautiful my alma mater is, I don't think I can describe it in words. Only good memories remind me of his miss.
