Lüht is a clan in China that is widely regarded as the main and oldest Hvetshran clan on the Asian continent. Since it is assumed that they originated from a smaller east European or central Eurasian clan, their history is usually divided in a European or Eurasian period called proto-Lüht (until a couple of centuries BC) and an Asian period called Lüht (from their migration to present day).
The name Lüht, derived from the Hvetshrenu word lüht (east), is a name that dates from their Asian historical period, where rather than calling themselves this, the clan members of Lüht were referred to as "Hvetshran living in the east" by their European counterparts. This became the common expression to refer to them with, carried over by solitary Hvetshran wandering through Asia and people who had moved to Lüht from clans such as Zrrv or Tßradj.
According to the most plausible theory, he clan from which Lüht most likely originated, was a small nameless clan that lived on the eastern side of where the gross of clans lived. Hvbetshranologists situate them on the central Eurasian continent, in modern-day Ukraine, southeastern Russia or Kazakhstan. Lüht was the result of this clan's move eastwards to China, where at that time did not live any other known Hvetshran clans yet.
In the era of proto-Lüht, the east Asian region had no Hvetshran inhabitants yet, besides small groups of less than ten individuals living a nomadic lifestyle. Because of the growing in both Hvetshran and human population on the European continent, migrating their hunting grounds to the Asian continent would likely have been a possible solution to not overlap with other clans' territories.
In or around the fifth century BC, proto-Lüht would have sent out a small group of members to their surrounding clans, which these clans, as is usually the case in an ethnic exchange, responded to by sending Hvetshran back in the course of the next few decades. Since the influx of clan members was larger than the outflux had been, this meant a growing number of inhabitants.
After several years of no immigrants, proto-Lüht set off eastwards. They probably settled for a year or two on several locations, before they found a location in present China which they made their first permanent residence. Not too long after that (approximately 10 years), they let a small group of members return to Europe for continued relations and exchange, but since Asian former nomadic Hvetshran joined Lüht, the clan's numbers did not decrease.
Hvetshranologists believe that some of the traces of formerly inhabited caves they have found in Nepal and Tibet belong to the temporary residences of Lüht's ancestors. This is because they contained bones of bigger animals, including carnivores, which showed teeth marks, however not enough to be proof of prolonged stay.
