In the morning of March 12, the "Civilized Proprieties Bookcrossing Activity" sponsored by Nanjing Civilization Office was held. In the future, residents can take civilized proprieties books free of charge in ten venues.

Bookcrossing Activity means people stick the unique labels on books and put these books in the public. People can take these books away and put them in other venues. The activity has ever been held in Shanghai, Changsha and Dalian.
