China's one-and-only museum for the red army's slogans that were written in the 1920s and 1930s opened Thursday in Hunan Province, said local authorities on Friday.

The museum, covering 14,000 square meters, houses 234 slogans in the sparsely-populated Yanling County, west of Jinggang Mountains, which was an important base for the Red Army in its early stages, said Zhong Dingjun, director of county's Cultural Relics Bureau.

Another 105 slogans, in the form of cartoons, paintings and couplets, can still be seen on the walls of old houses in the county, Zhong said.

Experts believe that many of the slogans were written by Mao Zedong, and were written about politics, military and economic policies at the time.

"The slogans are of great value for studying the history of the Communist Party of China and the Red Army," Zhong said.

Jinggang Mountains are known as the birthplace of the Red Army and the cradle of the Chinese revolution where the communist party set up its first revolutionary base.
