Well if you are talking about the manga maybe try to place the picture of the hand they show when they use terminology, maybe I could guess it.
Even though they follow special rules I assume the way of playing is similar. If you are Italian it might help you saying that you close the round with a combination similar to "ramino" or "scala 40". In Italy it is very much played in "Emilia" and "Lombardia"...you might look into it, it is a very addictive game hee hee.
Here you can find the most common rule found internationally
MahJong Rule in Italian
Here are some variations of the game...so that you can see how different mahjong can be (and these are only some of the official ones)
