Analysis of information sources in references of the Wikipedia article "Yuezhi" in English language version.
Among the Greater Yuezhi it appears that a lady was appointed to be the ruling queen on at least one occasion. "Zhang Qian zhuan" 張騫傳 (Biography of Zhang Qian) in the History of the Han records that after the king of the Greater Yuezhi was killed by the Xiongnu, his wife was appointed to be the queen.
The Yuezhi people conquered Bactria in the second century BC, and divided the country into five chiefdoms, one of which would become the Kushan Empire. Recognizing the importance of unification, these five tribes combined under the one dominate Kushan tribe, and the primary rulers descended from the Yuezhi.
This would seem to prove that the Yueh-chih of Chinese history – if they correspond, as supposed, to the Tokharoi of Greek history – were from that time established in Bactria, a country of which they later made a 'Tokharistan'.

In Noin-Ula (Noyon Uul), Mongolia, the remarkable elite Xiongnu tombs have revealed textiles that are linked to the pictorial tradition of the Yuezhi: the decorative faces closely resemble the Khalchayan portraits, while the local ornaments have integrated elements of Graeco-Roman design. These artifacts were most probably manufactured in Bactria
About "Khalchayan", "site of a settlement and palace of the nomad Yuezhi": "Representations of figures with faces closely akin to those of the ruling clan at Khalchayan (PLATE I) have been found in recent times on woollen fragments recovered from a nomad burial site near Lake Baikal in Siberia, Noin Ula, supplementing an earlier discovery at the same site), the pieces dating from the time of Yuezhi/Kushan control of Bactria. Similar faces appeared on woollen fragments found recently in a nomad burial in south-eastern Xinjiang (Sampula), of about the same date, manufactured probably in Bactria, as were probably also the examples from Noin Ula."
p.3: "These tapestries were apparently manufactured in Bactria or in Gandhara at the time of the Saka-Yuezhi rule, when these countries were connected with the Parthian empire and the "Hellenized East." They represent groups of men, warriors of high status, and kings and/ or princes, performing rituals of drinking, fighting or taking part in a religious ceremony, a procession leading to an altar with a fire burning on it, and two men engaged in a ritual."

The Shajing culture of the Early Iron Age. The sites of this culture have been discovered in the central part of Gansu Province (China). Seven big burial grounds and almost the same amount of fortified settlements (with walls made of compacted loess) have been excavated. Painted pottery, associated with the local tradition of Neolithic-Early Bronze Age, has been found at the early sites, but the Scythian-like artifacts constitute the core of this culture. This makes it possible to clarify the chronological limits of the culture as 900-400 BC, but probably with the later specific dates. Different suggestions have been made concerning the ethnic origins of the "Shajing people," who may have some connections with the Tocharian-speaking Yuezhi, the proto-Tibetean Qiang and Rong, or even with the Iranian Wusuns. The Shajing culture might have emerged from the interaction of all these (or close) ethnic and cultural components.
