Whether or not to wear a wedding ring depends mainly on the lifestyle habits and work environment of both parties. If one spouse is not accustomed to wearing a ring or cannot wear a ring due to work reasons, such as police officers, nurses, etc., then a wedding ring can be omitted. But in some interpersonal activities, it is best to wear a wedding ring to indicate one's married status.
How to wear a wedding ring
Internationally, both men and women wear wedding rings on their left ring finger after getting married.
Due to the ancient Chinese tradition of "men on the left and women on the right", some brides in China will wear their wedding rings on their right ring finger, while the groom will wear their wedding rings on their left ring finger.
