The De'angs have no written script of their own , and many of them have learned to speak the Dai , Han or Jingpo languages , and some can read and write in the Dai language . The increasing economic and cultural interflow between the Han and Dai peoples , as well as the migration of many Han people to the frontiers , taking with them advanced production skills and culture and science , promoted the economic development of Dai society . Due to long years of contacts and exchanges with the neighboring Han and Hui people , the Bonan people have borrowed quite a number of words from the Han language .
