Globally, Ronghai (荣海 , Ronghai , 容海 ) is a common primarily masculine, but scarcely female forename. The given name Ronghai is characteristic of China, where it is quite a rare predominantly masculine, but very infrequently feminine name, and India, where it is an extremely rare male name. Much less frequently, Ronghai is the last name as well as the forename.
