Where was Li Bai's "The Ancient Waves Running to the Moon" written?

Changan. A Journey on the Gulangyue was written by Li Bai, a famous poet in Tang Dynasty, in Chang 'an period. At that time, Li Bai was watching the full moon on Chang 'an night, so he was inspired by this poem. In this poem, Li Bai depicts a full moon hanging in the sky, sprinkling Yin Hui and illuminating the earth, and at the same time expresses his lofty aspirations and the spirit of pursuing freedom. This poem, with its fresh artistic conception, vigorous momentum and fluent language, became one of the representative works of the prosperous Tang Dynasty and had a far-reaching influence on the poetry creation of later generations.
