FAQ
Is 乐正 a common surname?
It is less common than names such as 李 or 王, but it is still a real and recognisable surname.
Can I use 乐正 as a foreigner?
Yes. A surname is optional, but if you want a full Chinese name, a common surname is a safe place to start. Check the full name out loud and make sure the given name does not create an awkward homophone.
