What do you mean the little finger is not cut? What do you mean you don't cut your nails?

If the little finger nail is long, it is often related to a person's luck. For example, if a person's little finger is very short and doesn't reach the third paragraph of the ring finger, then these people will leave the nails of the little finger longer and let the nails of the little finger exceed the third paragraph of the ring finger, and their fortune can be resolved. I hope this answer is helpful to you.
