Can feng shui-related things be retrieved and used after the fire?

After the fire, people all grabbed things from it. If they are useless, they will continue to use them. A little help is better than nothing. My parents have this kind of thing at home, and they have been using it since 1969, almost fifty years. They are all 90 years old, and there has been no special disaster or improvement in the past 50 years. When things are good, they are better, and when things are bad, they are almost.
