There are 8 north-south streets and 8 east-west streets 14 in Guo Cheng. Drainage ditches are set on both sides of the street, and roadside trees such as elm trees and locust trees are planted. Among them, six main streets leading to South Sanmen and connecting East and West Liumen are main roads, most of which are more than 100 meters wide. Suzaku Street is the widest 155 meters, which is the north-south axis of the city. Taking this as the boundary, the east of the city belongs to Wannian County and the west belongs to Chang 'an County.

The crisscross roads divide the outer Guo Cheng into 1 10 squares (called "Li" in Sui Dynasty). Each square has a different area, with a length of 500-838m from north to south and a width of 550-1125m from east to west. There is a fence around every square. Generally, there are four doors in a big square, and there is a cross street in it. In Little Square, there are two east and west doors, and there is a cross street, both of which are about 15 meters wide. According to archaeological excavations, Cross Street divides a square into four areas, and each area has a small cross lane, which divides the whole square into sixteen small blocks, including houses, official residences, temples and Taoist temples. All workshops are closed management, guarded by guards at the door, and a curfew will be imposed at night.

There are many Buddhist temples in Chang 'an, and Zongzhi Temple, Zhuang Yan Temple, Xingshan Temple and Du Xuan Temple all occupy the whole square. Other famous Jionji (Big Wild Goose Pagoda), Jianfu Temple (Little Wild Goose Pagoda) and Seiryuji also own large areas of land. During the archaeological process, the city also found many collections of Sui and Tang kilns, among which 27 1 piece of gold and silver unearthed in hejia village (Xinghuafang) is the largest and most valuable gold and silver unearthed in the Tang Dynasty since the founding of the People's Republic of China.

There are two markets outside the city of Guo, the East Market (called metropolis in Sui Dynasty) and the West Market (called Liren City in Sui Dynasty), each occupying two squares. The two cities are almost the same size, with a length of1025m from north to south and a width of 927m from east to west. The market has a wall with eight doors, and there are streets and streets along the wall, which divide the city into nine districts. Every district is surrounded by streets, and there are shops, restaurants, jewelry stores and handicraft workshops along the streets. Most of Chang 'an's businesses are concentrated in these two markets, and other workshops also have some scattered commercial facilities.

There are four ditches in Chang 'an city, namely, Ming Longshou, Qingming, Yong 'an and Caoqu, which introduce tributaries of Weihe River into the city from the southeast and west respectively to provide domestic and environmental water. The first three canals were dug in the third year of Huang Kai in the early Sui Dynasty (583), and the grass canal was dug in the first year of Tang Tianbao (742).
