New born babies were named "ayay" (a baby's crying), "shipo," "poyshi" (small excrement), "shion" (old excrement), etc. Children were called by these "temporary" names until the ages of two to three. They were not given "permanent" names when they were born. Their tentative names had a portion meaning "excrement" or "old things" to ward off the demon of ill-health. Some children were named based on their behavior or habits. Other children were named after impressive events or after parents' wishes for the future of the children. When children were named, they were never given the same names as others.
