The article discusses a unique monument of rock-art on the territory of Xinjiang - namely the petroglyphs of Kangjiashimenzi (Hutubi County). The person who began scientific investigation of this site in 1987 was Professor Wang Binghua. From that time, the issues of Hutubi petroglyphs became among the most popular topics in Chinese archaeological literature but only in a few publications in other countries and only one - in Russia. This article aims to fill this gap. The Kangjiashimenzi rock-art panel comprises 292 images of different size composed as a whole ensemble depicted using a counter-relief technique, with some grinding after. The images were given in quite stylized (dancing) poses. The male figures are often presented with an erect phallus. The picture also includes several coitus scenes. We supposed this ensemble in general served as a pictorial reflection of ancient mystery-plays connected with genus or tribal worships and with sacred wedding rituals. The main part of the petroglyphs dates to the Middle Bronze Age (circa first half of II millennium BC). On the territory of Xinjiang this period was presented by Xiaohe Culture. Within these rock-art engravings, two groups of petroglyphs, most likely, with later dates can be distinguished though they were very precisely incorporated into the ensemble. Images of ‘tigers’ one could connect with activity of nomad tribes of Saka (circa first half of I millennium BC), and antithetical figures of two horses - with some other nomad tribe of Yuezhi (circa II century BC). In any case, the monument with rock engravings has been created and used over quite a long time. It is very probable that Kangjiashimenzi was a functioning sanctuary, at least for the whole region.
