There was no need to make an appointment in advance in the Nightless City of the Great Tang. The tourists could go directly to the scenic area without prior arrangements. Although there was no need to make an appointment, it was a wise choice to make an appointment in advance considering the busy tourist volume and possible peak traffic. This way, they could avoid waiting in line.
The Nightless City Gate of the Tang Empire was located between the southern square of the Big Wild Goose Pagoda and the Kaiyuan Square, and it was about 1500 meters long.
The Nightless City was open 24 hours a day. However, after 23:00, the street performances were basically over. Some scenic spots and business districts in the Nightless City would be closed at night. For example, the business street and amusement park would be open from 8 am to 9 pm, while the cultural square and Tang Furong Garden would be closed before 10 pm. Therefore, although there was no specific closing time for Tang Nightless City, the street performances would basically end after 23:00 in the evening.
Tang Sanzang of the Nightless City was Xuanzang.
