 Based on a reconstruction of Yueban history, Lev Gumilev argued against a then-widespread view that the Rouran were synonymous with the "Avars" or "Pseudo-Avars" (who attacked the Sabirs before invading Eastern Europe), because the Rouran would have had to pass through the Yueban state to attack the Sabirs.No records address the Yueban religion, though Chinese annals depict some manifestations of religious rites and magic.A narration about the Yuebans tells about sorcerers, able to cause frost and rainstorm.
