Is Jiaxin a girl's name or a boy's name?

When I was at school, there was a Michele Monique Reis and a Michele Monique Reis in my class. The former is male and the latter is female, so I can't tell them apart. Every time we talk in class, the teacher calls the roll, and after the exam, we all wait for jokes. I still remember. I think you are also a boy. The word "Xin" consists of three golds, which means that the three golds are in full bloom. The word "heart" is named after a boy. What do you see? Wang Xin, Sun Xin and Lu Sanjin from Longmen Escort Agency. In fact, his name is Lu Xin, and the famous Yao Jiaxin is also a boy. But it does not rule out that girls can't use this word. I have a female friend by my side, named Xin Li. Is the landlord naming the baby? This Xin is not very pleasant to listen to. I recommend the word "letter" for reference only! ! !
