The author's description of the background city: Changle City described in the book is one of the cities in the fictional "Jing Tian" country. From Jing 'an, Jingling and Jingxi, which were the earliest and most widely known, to Changle, Anhai, Fang Jing and Qingrong, it was a country that gradually merged.

Changle in reality is a city near Fuzhou, Fujian, because I like to use this name. Please don't compare reality with books.
