Finding the truth of the past is difficult, decoding ancient mysteries (before mainstream historical records) is even more difficult. Those who do not take risks cannot find treasures, nor can they reset past matters that may cause us to reverse our beliefs to test. Ta Duc is such a researcher. Tạ Đức in early 2017, once again reappeared a piece of history with a closer look: "The origin and development of Dong Son bronze drum". Through that research, readers will see somewhat in the past about the aesthetic and religious life, about the migrations that took place on this land of Vietnam. For a long time and until now, there still exist different views about the homeland of Dong Son bronze drums.
