Alung is used for the eldest child and then Angeh, Avan, and Asit.   Unlike other cultures where titles are used only by the siblings, Cham culture differs in that the titles are used to describe the rank of the children from within the family and outside of it.  For example in Chinese a younger sibling will call his/her older sister “jiě jie” and no one else will call her by that title.  However in Cham culture, the eldest child will be called Alung by the siblings, the parents, and outsiders of the family.
