CHiNA?
CHiNA? is the "tag" of an unconfirmed Columbian who has left his or her mark in several buildings on campus. Most of the dorms and other buildings such as Mudd have this mark in the elevators, walls, ceilings and sometimes closets. It is unconfirmed but speculated that there is a connection to a student who appeared nude in Natasa Sesum's fall 2005 Calculus III class and remarked, "Free China... Free China?" Before dropping a flyer and leaving the class.
