In the evening, some friends organized a free hug event in front of the canteen. Having never experienced a free hug shin-dig, I was curious. It was awesome. The Chinese people were generally really confused. It took a bit for them to understand what we were doing (despite signs and costumes), but most were pretty willing to have a hug. I think that all the people we hugged now think that foreigners all give each other hugs on Halloween.
We went to a party at a pizza bar on campus. At first it was pretty lame. Just a bunch of excited Chinese freshman talking to us in English. After a bit though, we met some really cute Chinese girls and talked to them for a couple of hours in Chinese about many things: movies, sight-seeing, food. It's so satisfying to be able to talk to Chinese people about things other than "What's your major? Where are you from?" I feel like I can almost hold normal conversations.
Afterward, some friends went to a nightclub, but we went to someone's dorm room and watched the eternal classic "The Princess Bride"
