According to historical materials, Viet people was the first group living in Vietnam. And then other people came from the Southeastern Asian area. Almost of them are from China. Their ancestors migrated to Vietnam few hundred years ago. There are ethnic minority groups such as Khmer and Cham, descendents of inhabitants who lived in central and southern Vietnam before the area was conquered by Vietnam. The other groups are Muong, Pathen, Pu peo,etc. All of them are divided into 5 major groups following the language they speak: Austro-Asiatic, Mon-Khmer, Viet-Muong, Sino-Tibetan, and Austronesian.

Nowadays, Kinh (or Viet group) mostly base in plains, especially in the Red River Delta and the Mekong Delta. The ethnic minority groups locate in the mountainous areas. Each group has their own custom and tradition. However, they are all friendly and love peace.
