People greet eachother with a single handshake, and as a sign of respect, they will support the hands with their left hand. Children are addressd with their first names, but parents are addressed with the added prefix of Mai (meaning "mother of") and Baba (for "father of"). the way this works is the parent would have that prefix, depending on if they were the mother or father, added to the name of their child. So the translations would be "Mother/Father of Korra" if that was their child's name.
