In ancient times, it was the goddess of mending the sky, and now it is the pearl of Taihang. Where is this city?

It's Jincheng City, Shanxi Province.

Jincheng is one of the birthplaces of Chinese culture, leaving behind human sites such as Du Gao Site, Tashui River and Xia Chuan 20,000 years ago. It is the birthplace of myths such as the Goddess of Mending Heaven, One Mountain in Gong Yu, Shimen in Imperial Chishui and Chu Yu in Shang Tang.
