(December 14, 1965)
Secret and confidential communications, as well as security and guard duties, are of great importance. We must safeguard the Party’s secrets, prevent them from being exploited by revisionists, and avert the emergence of revisionism within our ranks. In the event of war, we must remain vigilant against all kinds of evil forces that might rise up to sabotage our cause. This message should be conveyed to the Central Confidential Communications Bureau and the Confidential Office, and also to the responsible officials of the Military Confidential Communications Bureau and the Broadcasting Administration, who must all pay close attention.
