Xinjiang Kuqa region (i.e. Guguizi), located at the crossroads of east-west traffic, is a famous oasis on the ancient Silk Road, a necessary place for the north of the Silk Road in history, and one of the important political, economic, cultural and trade centers in the Han and Tang dynasties in the western region. The "Book of Han and the Biography of the Western Regions" says: "Guizi Kingdom, Wang ZhiYancheng, went to Chang'an for 7,480 miles." There were 6,970 households, 81,317 mouths, and 21,76 victorious soldiers. Dadu Wei Cheng, Fu Guo Hou, An Guo Hou, Hu Hou, Hu Du Wei, Shu Du Wei, Left and Right General, Left and Right Du Wei, Left and Right Rider Jun, Left and Right Auxiliary Jun, two each of the East, West, South, and North Qianchang, three Hu Jun, and four translators. It is bordered by Jingjie to the south, Zhimu to the southeast, Yumi to the southwest, Wusun to the north, and Gumo to the west. Can be cast, there is lead. To the east, it is three hundred and fifty miles from the capital protector Wulei City. "In 60 BC, the Western Regions Capital Protectorate was established in Wulei (present-day Luntai County), and Xinjiang was incorporated into the Chinese territory and became an inseparable part of China. At the end of the Eastern Han Dynasty, the Western Regions Capital Protectorate was once moved to Yancheng; the Tang Dynasty established the Anxi Metropolitan Protectorate in Guizi Irolu City, which led the 22 capital protectorates in the Western Regions and the garrisons of the four towns of Guixuan, Yanqi, Khotan, and Shule. From the Five Dynasties to the Song Dynasty, it was called Guizi Uighur, and during the Yuan and Ming Dynasties, it was renamed Yili Baali. In the twenty-third year of the Qianlong Dynasty (1758), it was named Kuche and set up a minister of Kuche Affairs. In 1884, Kucha was directly subordinate to the Fumin Department, which had jurisdiction over the current Shaya and Xinhe counties. In 1902, Kucha Prefecture was reorganized into Kucha Prefecture, which belonged to Aksu Province and had jurisdiction over Shaya County. In 1913, Kuqa County was reorganized, and in 1922 it was subordinated to the Office of the Administrative Inspector of the Fourth District of Xinjiang Province. In 1950, it belonged to Aksu Prefecture and set up Kuqa Town. In 1971 it was subordinate to the Aksu region. According to research, the ancient city of Guizi is the "Yancheng" of Guizi in the Han Dynasty and the former site of the "Irolu City" in the Tang Dynasty.
Guizi guarded the middle section of the northern route of the ancient Silk Road, connecting trade and civilization between the East and the West, and was extremely developed in economy, culture and art, and also occupied an important position in the world economy and cultural history. The political, economic and cultural exchanges between China and the West on the Silk Road greatly promoted the social and economic prosperity of Guizi, and on this basis, the brilliant Guizi culture was produced and enjoyed a high reputation. In terms of music and dance, he is an outstanding representative of Western music and dance. As early as the Han and Tang Dynasties, Guizi was known as the "Western Music Capital" by the West, known as the "Hometown of Song and Dance", and the famous Guizi Music and Dance was born here. In terms of Buddhist art, it has a more ancient history of grotto art than the Mogao Grottoes, and the Buddhist murals and statues in the grottoes and Buddhist temple sites, as well as the Guizi and Chinese inscriptions are more eye-catching. Today, the Guizi region also preserves a large number of cultural remains containing ancient Indian Gandhara, Guizi and Central Plains Han civilizations, including ancient cities, cave temples and Buddhist temple sites, as well as various other types of sites and a large number of tomb groups. As representatives of the ancient Guizi culture and as an important part of Chinese culture, they still play a role in educating people with history.
As the seat of the Western Regions Protectorate of the Han Dynasty and the Anxi Metropolitan Protectorate of the Tang Dynasty, the Ancient City of Guizi was the political, economic, cultural and transportation center of the central government in the Western Regions during the Han and Tang Dynasties, and has an important historical position and academic significance in the process of Xinjiang's historical evolution and the great process of the great unification of the Chinese nation, and is of decisive importance to the study of the historical changes in Guizi, the evolution of the Central Plains Dynasty's governance of the frontier areas, and the economic and cultural exchanges between China and the West.
