All around the world, หลุน (Lun 
, Loun 
, หลุน 
) is quite a common epicene forename. The given name หลุน is characteristic of Eastern Asia, particularly Hong Kong, where it is quite a common primarily male, but very seldom feminine name, Mongolia, where it is quite a common gender-neutral name, and Macao, where it is quite a rare boy's name. Not in comparison with a country's population, it is commonest in India, Hong Kong, and Vietnam. Also, หลุน is the last name as well as the forename.
หลุน is also a name for the fictitious and mythical characters: Lun Tha , the musical character in the musical The King and I by Richard Rodgers.
