The research and analysis of the Bacsonian (the Bắc Sơn culture) sites and artefacts in the northeast mountainous regions, as well as other different sub-regions, show that there are particular features relating to specific locations and periods, in addition to the general and key characteristics of the Bắc Sơn culture. The Bắc Sơn culture is determined to date back to a period from 12,000 to 5,000 BP. A majority of the Bacsonian sites belong to the Early Neolithic, while the rest belong to the Middle Neolithic. The Bắc Sơn culture was created independently and has different origins to the Hòa Bình culture. Owners of the Bắc Sơn culture resided in and exploited the northeast mountainous region before the Hoabinhian people moved there. However, this is just a hypothesis that should be proved by more evidence, especially results of absolute dating.
