No I think he means names consists of 2 words: Ussually Vietnamese names look like this:
"Family name" "Middle name" "Name"
Some girls have 2 middle names, so their name consists of 4 words.
Some people don't have "Middle Name" like my mum. It's kinda rare. She is named after a mountain near Qui Nhon, so she doesn't have the regular style of name.
Sorry, my bad.
