Kyzlasov 1996, стр. 322: "The Juan-Juan state was undoubtedly multi-ethnic, but there is no definite evidence as to their language... Some scholars link the Central Asian Juan-Juan with the Avars who came to Europe in the mid-sixth century. According to widespread but unproven and probably unjustified opinion, the Avars spoke a language of the Mongolic group." Kyzlasov, L. R. (1. 1. 1996). „Northern Nomads”. Ур.: Litvinsky, B. A.
