Also known as Lou Pass or Taiping Pass, Loushan Pass stands 50 kilometers north of downtown Zunyi. As the main peak of the Dalou Mountains, it lies at the border of Zunyi and Tongzi counties. A strategic gateway connecting Sichuan and Chongqing to the north and controlling Guizhou and Guangxi to the south, it has long been a military stronghold.

Its name dates back to the Book of Han: Geographic Records by Eastern Han historian Ban Gu, who referred to the mountain as "Bulang Mountain". Late Qing Zunyi scholar Zheng Zhen verified that "Bulang Mountain" is today’s Loushan Mountain. The Tongzi County Annals record that in 876 (the 3rd year of the Qianfu reign of the Tang Dynasty), Yang Duan of Taiyuan led seven clans to recapture Bozhou, expel Nanzhao forces, and establish hereditary rule. His general Lou Dianbang was granted land here, and his son Lou Shan, together with Liang Guan (son of another general Liang Zongli), guarded the high cliff. The place was called "Loushan Liangguan", later simplified to "Loushan Pass". During the Ming Dynasty, when Bozhou’s Yang Yinglong (29th-generation descendant of Yang Duan) rebelled and was suppressed, the pass was renamed "Taiping Pass", but locals still use the original name.
