The origin of Neihuang place names?

Neihuang has a long history and outstanding people. Neihuang County was established in the ninth year of Emperor Gaozu, with a history of more than two thousand years. Neihuang is the earliest "ancient capital of the Four Dynasties" in China, where Zhuan Xu, Di Ku and Taiwu, the ancestors of China's "Three Emperors and Five Emperors", established their capitals, businesses and tombs, which is a holy place for Chinese children to seek their roots and worship their ancestors.
