why did vietnam descriptive name is tiny dragon of southeast asia?

Answer 1

This is a copy from the answer I gave in yout other question.

There are two possible reasons.

Depending on who you ask, the shape of Vietnam looks either like a fish or a dragon. The head (be it a dragon or fish) is the South where Saigon is and the tail in the North where Ha Noi is.

Another reason could be that tiny dragon is an accurate description of the people and the country. Vietnam is a small country that has fiercely defended itself for over a thousand years against several countries that are much larger.
