Introduction to the Manchu Historical and Cultural Corridor: The Manchu Historical and Cultural Corridor, with a total length of 560 meters and 503 paintings, is the longest semi-enclosed mural corridor in my country. The corridor displays Nurhachi's great achievements and the development of the Manchus in his life, including the origin of the Manchus, the unification of the Jurchen tribes, the rise of Nurhaci, the establishment of the Qing Empire, the Qing army's entry into the country, the unification of the country, and the end of the Qing Dynasty.
