The Wulagai Grassland in Xilin Gol League of Inner Mongolia is a rare and preserved original ecological grassland in the world. There is no industrial and commercial development here, and it has the reputation of Tianbian Grassland. The film "Wolf Totem" was filmed in Ulagai, and the town of the Corps was the main scene for filming. There is a sudden emergence of a small town on the grassland, and it still retains the strong style of the sixties and seventies. This is not to be of interest to tourists. The town of the regiment was built mainly for the film "Wolf Totem", and many scenes in the movie can be found here. Most of the houses are built with bricks and clay. They are relatively simple and functional, including veterinary stations, hairdressers, canteens, cinemas and other unique houses. After the film was filmed, the town was handed over to the local tourism bureau for management. Now it has become a scenic spot in Ulagai. After many tourists watched the movie, they wanted to come here to find the place where the male lead Feng Shaofeng lived. There is a photo studio in the town of the regiment. Renting clothing is their main source of income. Most of the tourists here will spend 20 yuan to rent a military uniform. After wearing it, it is very suitable for taking pictures. . In fact, this place of the Urugai Grassland once belonged to the Inner Mongolia Production and Construction Corps in the 1960s and 1970s. All buildings are open and can be visited. The interior still retains the appearance of 40 or 50 years ago.
