History

In 312 BC the state of Qin set up Gudao County (故道县), covering today's Liangdang and Feng County (凤县) in Shaanxi. Its mountain plank road to Hanzhong and Shu was the "old road" (故道) by which Emperor Gaozu of Han (汉高祖) led troops out to defeat Zhang Han (章邯) at Chencang (陈仓). The name Liangdang first appears in 474, under the Northern Wei. In 995 the county seat moved from Danhepu (单河铺), now in Feng County, to Guangxiang town (广香镇), the present county town. Merged into Huicheng County in 1958, Liangdang was restored at the end of 1961 and moved from Tianshui to Longnan in 1985.

In April 1932 Xi Zhongxun (习仲勋) launched the Liangdang Mutiny (两当兵变), which the county government calls the first shot of worker-peasant armed struggle in Gansu and the birth of the province's first Red Army unit. Liangdang is also the home of the Tang official Wu Yu (吴郁), and Du Fu (杜甫) and Lu You (陆游) both left poems on the area. Du Pengcheng (杜鹏程) wrote "Night Walk through Lingguan Gorge" (夜走灵官峡) here, and the county keeps a genealogy of the calligrapher Wang Xizhi's (王羲之) family. Remains of a Western Han county town survive, along with a street of Ming and Qing buildings.

What to see

The county has two national 4A scenic areas: the Liangdang Mutiny red culture area (两当兵变红色文化景区) and the Yunping Three Gorges (云屏三峡). The Liangdang Mutiny Memorial Hall (两当兵变纪念馆) is a national patriotic education base. Local lore includes legends of Zhang Guolao (张果老), one of the Eight Immortals, and the Liangdang work songs (两当号子).

Liangdang calls itself the home of wolf-tooth honey (狼牙蜜乡), and Liangdang wolf-tooth honey (两当狼牙蜜) is a Chinese geographical-indication product. Walnuts, edible fungi and herbs are also grown.
