Around the globe, 开 (开 
, Khai 
, Kāi ) is a common epicene given name. The first name 开 is characteristic of Mongolia, where it is a common girly name, Brunei, where it is quite a common principally boy's, but scarcely girly name, and Grenada, where it is quite a common male name. Not in comparison with a country's population, it is the most numerous in China, Vietnam, and Mongolia. More frequently, 开 is the last name as well as the forename.
