In the world, 六 (Sau 
, 六 
) is a widespread principally feminine, but very infrequently male first name. The forename 六 is habitual in Hong Kong, where it is quite a common dominantly girly, but seldom male name, Macao, where it is quite a rare female name, and India, where it is quite a rare predominantly girly, but scarcely boy's name. Measured by absolute frequency, this name is the most popular in India, China, and the United States. More frequently, 六 is the last name as well as the forename.
