In the entire world, Huaixin (怀新 , 怀信 , 怀欣 ) is quite a common principally boy's, but very seldom girly forename. The given name Huaixin is habitual in Eastern Asia, particularly China, where it is a rare principally masculine, but scarcely female name. Very seldom, Huaixin is the last name as well as the forename.
