"Eight hundred years is long enough for much to change as new things appear and disappear with the passage of time. But for this clan here, tradition is kept regardless. Their homage to the ancestor and their dedication is what makes them who they are," says Wang Mangmang, Inner Mongolia Autonomous Region.

Grand sacrificial rituals are held every season, and there are more than thirty smaller ones throughout the year. Hosting worship ceremonies for tourists is an every day job for Bi Lige.

But while paying homage to the ancestor, many do not know about Dalhuts, or how difficult it has been to keep the tradition going.
