Изгледа да хипотеза о Хсианбејима (Сербима) уопште није толико невероватна колико се на први поглед чини. О прихватању централноазијских (хунско-аварских) политичких модела од стране словенских племена је писао историчар Хјун Џин Ким у својој књизи "The Huns":
"Likewise probable is the impact of the Avars on the Polabian Slavs in what is now modern eastern Germany. We find among them the now familiar principle of collective rule among members of the royal clan. Thus the Polabian Weletians in the eighth and ninth centuries AD had a supreme prince Dragowit (rex) who had authority over other ‘reguli’ in the tribal confederacy/kingdom. Later the supreme prince Liub (totius regni summa) is shown to have shared his authority with his brothers, each of whom controlled a regio (a federation of clans headed by a prince). Interestingly there were four principal regiones/sub-divisions among the Weletians as among earlier and contemporary steppe confederations. As in any Inner Asian steppe state in this Slavic political entity in the middle of Europe a single dynasty had exclusive rights to the princely throne. Not only these Polabians, but also many of the other northwestern Slavs such as the Sorbs and the Abodrites were also likely to have been heavily influenced by former dissidents of the Avar-Hun Empire who moved to their region."
"The Slavic state of Greater Moravia that arose after the dissolution of the Avar Khaganate at the hands of the Franks and Bulgars in the ninth century AD was also, not surprisingly, affected by Avar political precedents. The Moravians are known to have adopted the Avar title of zhupan. In Moravia and also later in Poland a system of fraternal rule and succession developed which gave each of the king’s sons his own appanage as in the Hunnic and Avar Empires. However, despite the appearance of territorial divisions and fragmentation, like in the Hunnic and Frankish contexts we have observed earlier, these Slavic states maintained the outward political and territorial integrity of the state."
Потом, најзанимљивији део:
"In southeastern Europe the Hunnic impact on the local Slavs is also palpable, this time via the Bulgars. The title and institution of zhupan, noted above among the Moravians who were themselves imitating the Avars, was a common Inner Asian political title. It was used for instance in the White Hun Hephthalite Empire to refer to a minor official. The title became the established designation of the ruling prince in medieval Croatia and Serbia via most likely a Hunnic Bulgar filter or less likely via the Avars. The South Slavic title ‘ban’ may also derive from the name of the Avar Khagan Bayan. The South Slavic and also later east Slavic aristocratic class system of boyars was likewise a borrowing from the Bulgar Huns. Furthermore, the Croats and Serbs would in the typical Inner Asian manner use colour designation for their political divisions. We learn from Constantine Porphyrogenitus about the ‘White’ Croats and ‘White’ Serbs close to the realm of the Franks."
"The strikingly Inner Asian political organization of the Croats and Serbs allows for some interesting conjectures about their origins. An Inner Asian Sarmatian origin for the Croat and Serbian ruling elite has already been postulated. However, the remarkable similarities between the Croatian foundation legend of the five brothers and the history of the five sons of the Bulgar Hunnic ruler Kubrat, the variation of whose name has been suggested as the etymological origin of the ethnonym Croat, deserve greater attention and research. Also deserving of further scrutiny is the remarkable similarity between the name Serb and the name of the Mongolic Xianbei, in Early Middle Chinese: ‘Serbi’. The possible connections between the name Avar and the name of the Mongolic confederacy Wuhuan (in Early Middle Chinese: Agwan(r)) and the name Sabir with the name Serbi (Xianbei), have already been discussed earlier in the book. The Wuhuan (Avar) and the Xianbei (Serbi) were members of the same united Donghu confederation that was conquered by the Xiongnu (Huns) in Inner Asia. If the Avars of Hungary are indeed to be ultimately associated with the Wuhuan, then the association of the ruling elite of the neighbouring Serbs with the Xianbei/Serbi might not be a wild conjecture."
Има овде више занимљивих момената:
-полапски Словени су преузели хунско-аварске (централноазијске) политичке традиције вероватно у додиру са Србима који су се доселили из Подунавља, из срца Каганата, што је и археолошки видљиво преко рјусенске културе (краљевска династија, дељење власти међу браћом додељивањем сваком понаособ територије којом влада, дељење територије на четири дела, итд.);
-титула жупана и бана, хунског и/или аварског порекла, раширена од Велике Моравске до Хрватске и Србије;
-употреба боја као ознаке за територијалну организацију (црно-север, бело-запад, црвено-југ, зелено/плаво - исток), "Бела Србија", "Бела Хрватска", типичан централноазијски мотив;
-невероватна сличност имена прото-монголских Хсианбеја/Серба (први облик је из модерног кинеског, а други из старокинеског) и Срба; такође се конфедерација племена Вухуан, који су били блиски Хсианбејима/Сербима, на старокинеском чита као Агван(р), дакле постоји могућа веза са Аварима.
