Unmarried people can wear the ring on their left little finger when wearing it.
Because in the ring wearing method, there is a saying that "the left hand represents marriage, and the right hand represents love", which means that all wedding rings are worn on the left hand. Therefore, if you are an unmarried person wearing a ring, you can wear it on your left little finger, which indicates that you currently have no plans to get married and want to live alone, and also represents your attitude. If you don't have such thoughts one day, you can take off the ring on your left little finger.
But the fact that unmarried people wear rings like this does not mean that they are currently single. Some people in love will wear rings on their left little finger, just to show their attitude of not wanting to get married.
