The Kung Fu he were practicing is 北少林拳 and he studied that under an American teacher. In fact, it's a registered student organization, kung fu club, in UIUC. I am not interested in 北少林拳, though, I will take a look at it.
After the conversation with him, I left and passed by the under-graduated library. Actually, I have been looking for that for a long time because I want to borrow some DVD in there. It seems that the library is built in memory of president James of US of American. Some of his words is carved around the top of the patio. I found this building interesting because it is built totally underground. The only portion above ground is its entrance. I guess it is because that this library is for "under"-graduated students, it is then built to be "under"-grounded.
