A ring is a kind of ribbon-shaped decorative jewelry, which can be worn on your finger. The ring can be worn by both men and women, and the material can be metal, gem, plastic, wood or bone. People in China wore rings about 4000 years ago. [1] By the Qin and Han Dynasties, it was very common for women to wear rings. Rings were often called "rings" in ancient times, but they were not called "rings" until the Yuan Dynasty. Throughout history, rings have been regarded as a symbol of love. The ring on the ring finger of the left hand is considered a wedding ring. Less and less countries and regions wear wedding rings on the ring finger of the right hand. In many areas, wearing it on the index finger of the left hand is considered as courtship, the middle finger means love, and the little finger means that we are not in love or single for life. In ancient Rome, rings were used as seals and symbols of power.
