Historical Origin
The sacrificial activities in Inner Mongolia are various: offering sacrifices to the sky, god of fire, ancestors, Aobao, etc. Among them, offering sacrifices to Aobaos are the most important one and it demonstrates the people of various nationalities living on the grasslands together. In ancient times, the ancestors of the Mongolian people revered the heaven and earth as the sources for human living and multiplying, so they worshiped them devoutly. Since people didn’t know what gods of heaven and earth looked like, they piled up stones (Aobaos) that served as the symbols of gods. By offering sacrifices to Aobaos, they prayed to gods of heaven and earth for a bumper harvest, thrifty animal husbandry and a peaceful life. There is another legend that explains the origin of Aobao. According to this saying, the prairie is so vast and boundless that people could easily lose their ways in the past; thus, they piled up stones as road signs. This was how Aobaos came into being. Later, Aobaos were gradually regarded as places where gods lived in and the people started offering sacrifices to them. In the past, each region, county, village and temple had its own public Aobao and the rich also had their own Aobaos with many names. Aobao, in the Mongolian people’s eyes, is a sacred place. In the old days, when embarking on a long journey, people would dismount their horses and pray to Aobaos for a safe trip once they saw one. They would later add several stones or a handful of earth to the Aobao and then mounted up their horses to continue the journey. It was in the Qing Dynasty that the custom of offering sacrifices to Aobaos annually with each tribe as a unit.
Sacrificial Activities
As the customs and traditions of the herds vary greatly in different regions, not all the time and forms of offering sacrifices to Aobaos are the same. Generally, the time for offering sacrifices is in late May and the beginning of June in Chinese lunar calendar, and sometimes in July and August (in Chinese lunar calendar). During this time, the water is abundant, the grasses are lush and the herds are robust. A single region can offer sacrifices by itself; some regions can jointly do this. The Siklingelei County is the place where the tradition of offering sacrifices to Aobaos is well-preserved.
