Where is the throat of Yunnan and the belly of Guizhou?

Anshun, chosen by the questioner/kloc-0 years ago, is one of the earliest developed areas in Guizhou history. The Qin dynasty began to build a "five-foot road" with carriages, and the Yuan dynasty began to build towns. During the Hongwu period of the Ming Dynasty, it was officially named "Anshun House" (formerly known as "Adabu"), and in the Ming and Qing Dynasties, "commerce flourished in the whole province". The strategic position is important, and it is known as "the belly of Guizhou, the throat of Yunnan, and the lips and teeth of Shuyue". Comrade Wang Ruofei, an older revolutionary, was born in Anshun. Wang Ruofei's former residence is now a national patriotic education base and a national red tourism classic scenic spot. The first expressway in Guizhou history was built in Anshun, and the first high-grade highway and the first expressway were also built in Anshun.
