Andronovo has been regarded as one of the most powerful cultures in Central Asia, which reflected frequent cultural interflow, people migration, and technique diffusion on the Bronze Age Eurasian steppes. In the past decade, many new discoveries in Xinjiang, such as Adunqiaolu and Jartai, have drawn broad attention to the communication of the Andronovo culture in the central Tianshan Mountains. However, systematic study is still insufficient on the communication and influence of the Andronovo culture or the “Andronovo phenomenon” along the Tianshan Mountains. Based on our comprehensive investigation of tomb structure, funeral rituals and assemblages, this article reclassifies relevant Andronovo remains in Xinjiang into five categories. Two categories represented by the Xiabandi cemetery and the Adunqiaolu show clear resemblance to those at Semirech’ye in all aspects, which indicated people in these regions may have maintained close and consistent interaction. Other three categories in the Kuokesuxi and Tangbalesayi cemetery have different tomb structures and funeral rituals from those typical discoveries of the Andronovo cultures in Central Asia in spite of the their similarity in pottery and bronze ornaments, which can be considered as the result of product exchange or technical communication, rather than population migration. New discovery of the Baigetuobie cemetery with evidence of tomb structure, dating, and human genetic features in the Balikun grassland suggested that there might be a small group of people, probably came from the central Tianshan Mountains or Semirech’ye or further west, had migrated to the Eastern Tianshan Mountains about 1600 BC, which was likely facilitated by the relatively warm and humid environment. They had preserved their traditional tomb architecture and were not active in cultural interaction and population fusion with people of Hami Oasis in the south. Due to some reason unknown, people of Baigetuobie had faded away from Balikun grassland after a short time.
