  Tày-ized Vietnamese among the Tày
  A part of the modern-day Tày population encompasses Tày-ized Vietnamese who live mainly in what is now Lang Son. These Tày-ized Vietnamese have their origins traced back to the Vietnamese living further south in the deltas of the Ca, Ma, and Red Rivers, e.g. Nghe An, Nam Dinh, etc. dispatched to the Sino-Annamese border by Annamese imperial governments to serve as governmental officials and local leaders (phiên thần thổ ty). These people were then forbidden to return to their home areas. Eventually they got assimilated into the indigenous Tày surrounding population. Their common surnames include Vi, Nguyễn Đình, Nguyễn Khắc, Nguyễn Công, Hoàng Đức, Hoàng Đình, etc. This practice started in the 15th century and ended in the early 20th century. Vi Văn Định is an example of these Tày-ized Vietnamese in the 20th century.
