You can't wear someone else's ring if you find it.
First, the reason why you can't wear the ring you found is because there is a saying in the older generation that the ring discarded by others may bring disease or bad luck. If you find someone else's discarded ring on your body, you will be infected with bad luck or disease, which will affect your health or fortune.
Second, the handling method of picking up the ring When picking up the ring discarded by others, according to the older generation, if you want to keep the ring for yourself, you can throw a dollar at the place where you found it. This means buying out the ring so that it has nothing to do with the former owner, and you can become the new owner of the ring without being contaminated with bad things.
From the perspective of real life, it is best to find a way to contact the owner after finding the ring. It is suggested to post the lost and found in the place where the ring was found, and explain the lost and found situation and personal contact information in words. You can wait for the owner to contact you, or you can directly give the ring to the police station.
