What is the legendary origin of the naming of Shexian, a famous cultural city with a thousand years?

Time goes by and times change. At that time, the word "Mao" of Qin Shihuang accurately predicted the development and evolution of this land. From the initial Zhu Chengli to the Huizhou cuisine, Huizhou merchants and Huizhou architecture that spread in the Ming and Qing Dynasties, they have been handed down from generation to generation and are still talked about by people. Therefore, Shexian's reputation as "the hometown of China emblem culture" is not a hollow name, but the result of thousands of years of cultural precipitation. The legendary origin of the name of Shexian, a thousand-year-old cultural city, when we once again set foot on this ancient land of Shexian, the sense of ancient rhyme of historical cohesion has never changed, as if it were still the same. Nowadays, more and more tourists come here for the Spring Festival or holiday, stop in front of spectacular archways, houses and mansions, and look for the footprints that Qin Shihuang once visited. While intoxicated with the antique beauty, they can't help but sigh "a county through the ages". Appreciating the unique scenery of "a county through the ages" has become one of the main reasons why tourists choose to spend the Spring Festival in Shexian.
