The former site of Tunguska Brazil City, a military town under the protection of Anxi Prefecture, was built in the Western Jin Dynasty in ancient China, with an east-west direction of 250 meters and a north-south width of about 230 meters. There are battlements in the four corners of the ancient city, which are huge and well preserved. In the twenty-second year of Zhenguan in the Tang Dynasty, Anxi Duhu House was established here, and there are four castles at the southern foot of Tianshan Mountain, which belong to Anxi Duhu House and "Anxi Four Towns".
When the Anshi Rebellion broke out, the Tang Dynasty urgently mobilized a large number of troops from Anxi, the capital city, to defend the four towns of Anxi, leaving an extremely tragic sum in the long history. At present, the site protection is relatively complete, so that more people can understand the history of Xinjiang. Xinhe County invested a total of 328 million yuan to build this Tang Anxi Dadufu Cultural Industrial Park, which covers an area of about 600 mu. The ancient city was built in full accordance with the former site of Tunguska West City, allowing visitors to experience the magnificent ancient architecture.
The completed ancient city is magnificent, surrounded by reeds and breezy in the autumn wind, which shows the long history of the ancient city. Perhaps many people have long forgotten this tragic history and the brave Anxi army. However, the rebuilt Tang Anxi Dadufu Cultural Industrial Park vividly presents the past history and makes people feel the courage and persistence of the team "Anxi Army" under the rule of the Tang Empire.
