About a (possibly) Korean sentence...

Korean doesn't use the roman alphabet.

As far as I know, the only asian language that uses our alphabet as standard (with tone marks) is Vietnamese.

In Vietnamese 'han' means 'verdigris'

For 'verdigris' I've found

1. a blue or green powder used as a paint pigment
2. a green patina that forms on copper or brass or bronze that has been exposed to the air or water for long periods of time

OR

'Verdigris'

A river, about 451 km (280 mi) long, of southeast Kansas and northeast Oklahoma flowing generally southward to the Arkansas River.

Can't find Ayo, but ao means.

noun

* Pond


verb

* To measure roughly, to measure approximately
o ao thúng thóc
to measure approximately a basket of paddy

thanks, buddies.
