Introduction to the No. 1 Aobao in the world: "Meeting in Aobao" is a well-known Mongolian love song. This song was sung throughout the land of China from Bayan Hushuo Aobao. In the 1950s, Beijing Film Studio's first grassland-themed film "People on the Grassland" started filming on Bayanhushuo Aobao Mountain. The theme song "Aobao Meeting" in the film is still widely sung today. In order to commemorate the first film shot on the Ewenki grassland and promote the Ovo culture, the people of the grassland asked Mr. Malaqinfu, the original author of the film's novel, to inscribe a stone tablet here with the inscription "One Ovo in the World".
