Just a scroll

I found a scroll hanging upon the walls in the Vietnamese restaurant Saigon Pho. The calligraphy was illegible, so illegible that I could't tell if it was in asian characters or the ordinary american alphabet writing. The translation for the first scroll says this:

People can go to many places,

But there is only one place

That can come back. 

It's home

I assume it must be some sort of Vietnamese script. Whatever form the writing is, you can tell that the writer infused art with each stroke of the brush. But to be honest, this scroll is very confusing. Besides the style of the characters, you can't tell whether the direction of the writing follows the horizontal form of the Western tradition or the vertical approach of the the Eastern tradition. Although the meaning of the words are very clear, the artistic aspect of the scroll is very puzzling.
