How old does "Fu Nian" mean?

This is a fortune-telling term, which means to give it to the old. That is, there is still a time between the two fierce years, and we should be careful every year, not sure which year it is. Bad years are: sixteen, fifty-five. In other words, there is still a disaster between the ages of 16 and 55, and its owner should be careful. This is the result of many fates.
