To guarantee the safety of broadcast work is one of the key points concerned for the Eighteenth CPC National Congress. On April 26, 2012, the inspection team from Provincial Administration of Radio Film and Television supervised Chenzhou broadcast work.
 

There are two TV & FM rebroadcasting stations available in Chenzhou like Sizhoushan and Suxianling, which work as TV signal transmission for Chenzhou city and other cities and counties covering 10 million people's TV signals and 12 million people's radio signals. China National Radio, CCTV, Hunan Radio, Hunan TV and Chenzhou local radio and TV signals are transmitted from the two stations.
Chenzhou took the action earlier to inspect the facilities of the two stations, especially for the transmitter performance index, amplitude-frequency characteristic, machine-running state and etc. in order that national, provincial and municipal programs could be well presented during the Eighteenth CPC National Congress. During the important periods, Sizhoushan and Suxianling station can only use the signal transmitted by the dedicated optical cables, microwaves, and "Central Star 6B"satellite, while other signals are forbidden.
