What is Nanniwan? Where is it?

Nanniwan is a narrow valley, located 45 kilometers southeast of Yan 'an City, with wild animals and no one to live in. 194 1 in the spring of, due to the economic blockade imposed by the Kuomintang reactionaries on the Shaanxi-Gansu-Ningxia border region and the anti-Japanese base area at that time, external materials could not be brought in. Therefore, the Central Committee of the Communist Party of China ordered the 359th Brigade of the Eighth Route Army to enter Nanniwan to reclaim land for production and save themselves. Without a room, dig a cave by yourself; No vegetables, dig wild vegetables to eat; Without tools, they make their own hoes and shovels. They planted crops on the barren hills with amazing perseverance. In just three years, Brigadier General Wang Zhen led the 359th Brigade to carry forward the revolutionary spirit of "self-reliance and hard struggle", and turned Nanniwan, which was full of thorns and desolate, into a great south of the Yangtze River with crops everywhere and flocks of cattle and sheep. Now, Nanniwan provides tourists with a large number of terraced fields, the exhibition hall of Nanniwan's great production movement, the former residence of Comrade Mao Zedong when he visited Nanniwan, Jiulong Spring and the Martyrs Monument. Among them, the "Nanniwan Mass Production Campaign Exhibition Hall" introduced the process of Nanniwan Mass Production Campaign in detail through objects and pictures.
