Who can tell me whether the phoenix in Shanxi is Datong or Jincheng, and the origin of this name?

Phoenix Legend: According to legend, in ancient times, there was a hunter named Wang Shan. One day, he saw a phoenix flying from north to south. He had never seen such a gorgeous bird, so he bent his bow and shot it down. The phoenix was injured and its feathers fell. When the feather landed, a big city suddenly appeared on the flat ground, from which Datong came, so Datong was also called Phoenix! In Datong, you can also see: Changbeiguan, Short Nanguan, Dongguan and No Xiguan. That's because Phoenix's right wing was shot. There is also a legend that there is a phoenix in the heavenly palace. After seeing all kinds of pleasures in the world, it has the idea of thinking about the lower bound. One day, the Jade Emperor found that there was a phoenix missing from the Heavenly Palace, so he ordered Jiro to go down to earth to look for it. Jiro found Phoenix enjoying himself here in Datong and had to order him to catch it, but Phoenix enjoyed it here and never wanted to go back. When Erlang meets the Jade Emperor, the Phoenix will stay in Datong forever, and Datong is called Phoenix, which is also a blessed treasure city.

The cultural landscape of Datong is rich and unique. There are more than 200 ancient buildings, sites, tombs and battlefields. There are 7 national key cultural relics protection units and 22 provincial cultural relics protection units. Hengshan Mountain in Beiyue, Kong Xuan Temple, Yungang Grottoes, Huayan Temple, Jueshan Temple, Jiulongbi and Kannonji are all famous tourist attractions.
