The Hohhot–Nanning corridor is a proposed high-speed railway in China running from Hohhot in Inner Mongolia to Nanning in Guangxi. It will pass through the cities of Taiyuan, Zhengzhou, Xiangyang, Changde, Yiyang, Shaoyang, Yongzhou and Guilin. Introduced in 2016, the corridor is one of the sixteen railway lines proposed under China's "Eight Vertical and Eight Horizontal" network.
