About my full name: How to write and how to call

For easy, If you want to mention me in a digial writing stuff, just type "nvcnvn" thats my prefer nickname. But if you need to write my name down or understand about the structure, here is it:

My full-formated name: Nguyễn Văn Cao Nguyên

Nguyễn [ŋuĩən] is my family name. All Vietnamese's name begin with name of the family...and maybe that our "philosophy", family come first.
Nguyễn is the most popular family name. Around 40% of Vietnamese have this family name, the 3-next-popular share 30% of total. So it a bad Idea to call a person by family name in a crowded room.

Văn is my middle name, a very popuplar middle name for male.

Cao Nguyên [ŋuiən] is my given name, note that Nguyên is different with Nguyễn, you can see a little accent on the "e" character.
Cao Nguyên in English is "highland".

The phonetic I write may incorrect, so here I speak my name:
