Precious bowls and dishes

Before I was born, our family used bowls which are made of some special materials to be used in family rituals. My great grand father thought that his offspring should consider these bowls precious, so he inherited these bowls to my grand father. My grandfather kept this in mind and when the Korean war broke out, he took these bowls with him when escaping the city. He left other things in his house because he couldn't pack all the things. During the war period, we had to do our family rituals and had to use these bowls to put food in them to pay respect to our ancestors. Korean
war finally ended and my father inherited these bowl from my grandfather and still he is using these bowls when we do family rituals. My little brother will bequeath this bowls and he will cherish them, too.
