It is well Known that the Tuque-Turks had various relations with the Sogdians and the Chinese. The royal family of the First Tuque Qaghanate of the eastern territory received a stela on stone tortoise and roofing tiles from China, inscription and probably funeral pantings from the Sogdians. The Custom of standing balbals to the east was nomadic origin. But they did not accept human and animal statues. After the collapse of the First Qaghanate, the qaghan family of the Xueyantuo might have erected roughly made human statues as balbals and accept animal statues from China. At the beginning of the Second Qaghanate the royal family accepted human statues of attendants from China but did not make statues of the dead qaghan and qatun like China. And then they made statue of the dead couple of their ruler, probably influenced by the Sogdians. This was a unique custom of the Tuque, not coming from China. Turkic, Sogdian and Chinese cultures gave influences to each other in the 6th-8th centuries. This situation was a character of early mediaeval history of eastern part of Eurasia.
