Where is the Datang city that never sleeps in Xi 'an?

As far as I know, the city that never sleeps in Datang is at the foot of Big Wild Goose Pagoda in Yanta District, Xi City, Shaanxi Province. It starts from the South Square of Big Wild Goose Pagoda in the north, ends at the ruins of the Tang City Wall in the south, ends at Ci 'en East Road in the east and ends at Ci 'en West Road in the west. The plot is 2 100 meters long from north to south and 500 meters wide from east to west, with a total construction area of 650,000 square meters.
