The Issue of Secrecy Warrants Our Extreme Attention
(September 1, 1950)
Comrade Chen Yi [1], and inform Rao [2]:
Regarding the various issues discussed here, when you draft the telegram, for the sake of secrecy, please send it via wired telegraphy, not by radio. Henceforth, for all confidential telegrams, please pay attention to using wired telegraphy, not radio. Only non-confidential ones may use radio. This applies to the Party, government, and military alike. The Party, government, and military should also do the same with lower levels: wherever wired telegraphy equipment exists, use wired telegraphy, so as to achieve the purpose of secrecy. At this time when the struggle between the enemy and ourselves is increasingly acute, the issue of secrecy warrants our extreme attention.
