Within the Chinese Communist Party (CCP), some Party units have established a largely unknown network of writing teams which propagate the policies or perspectives of a particular unit by publishing feature articles in Party journals. These writing teams often make use of a pseudonym in the form of a person's name, leading outsiders to believe that the work is written by a journalist. In fact, the pseudonyms of the Party unit writing teams function as a form of secret code. Through this code, inner Party members can recognize which unit's views an article reflects. In order to reveal exactly which units the codes represent, we have collated the names of over 20 writing teams. In addition, we provide an introduction to the functioning of the writing teams and the manner in which articles are produced. Finally, we propose that the CCP's mechanism of “propaganda codes” is gradually undergoing the process of institutionalization.
