    I took the Harvard Summer School program in my vacation. During my stay there, I spend a lot of time studying in the main library Widener. I enjoyed myself in the ocean of knowledges, either doing research for my papers or read special edition books. The library, which it is named after its donor Harry Widener, stands right next to the Emerson building of philosophy. Opening a pair of heavy yet elegant metal doors, I was immediate bathed in warm light. I wandered around the library, fascinating to find one treasure after other.
