Ancient capital name

(1) Chang 'an, the capital of the Western Han Dynasty, was changed to Luoyang after the Eastern Han Dynasty, so people in the Eastern Han Dynasty used to call Chang 'an Xijing and Luoyang Tokyo.

(2) Yang Dijian named Luoyang Tokyo, so he called Chang 'an Xijing.

(3) In the second year of Tang Xianqing, Luoyang was the capital and Chang 'an was the capital, so it was called Xijing. In the first year of Tianbao, it was named Xijing; In the second year of Germany, it was renamed Zhongjing.

(4) Tang Zhide recovered two Beijing cities in two years, both of which were Chang 'an. Because Fengxiang was the residence of Su Zong when the two capitals were not restored, Fengxiang County was changed to Fengxiang House and Xijing was built. In the first year of Shangyuan, Beijing was abolished.

(5) When Nanzhao King consulted the Cabinet, Yitai Square (referring to Bacheng, Ma Yang) became Xijing, and Shilong proclaimed himself emperor and was renamed Zhongdu.
