In the world, Jianzeng (建增 , Jianzeng ) is quite a common predominantly masculine, but very infrequently girly first name. The first name Jianzeng is habitual in Eastern Asia, particularly Taiwan, where it is a rare male name, and China, where it is a rare predominantly masculine, but scarcely feminine name. Much less frequently, Jianzeng is the last name as well as the forename.
