The change of individual roles runs through the whole life cycle, so people lose some old roles while gaining new ones. This replacement of old and new roles is called role transformation. Role transformation is often accompanied by role conflict. Such as retirement, divorce, etc. Some over-role ceremonies, such as adult oath, graduation ceremony, wedding celebration, etc. , can make the role change easier for individuals to tell others that their status has changed and new expectations are appropriate. At the same time, these rituals also enable individuals to adjust their behavior accordingly.
