扎比情坚
[zhā bĭ qíng jiān]
The term 'Za Bi Qing Jian' seems unique and unconventional. In literal sense, '扎'(Za) is used sometimes to denote pain, and '坚定不移'(Bu Dong) means firm and resolute. So perhaps this nickname suggests that the user is determined in love, despite enduring heartache. Note: '扎'is also commonly used as profanity, but that doesn’t seem suitable for a username, so the former meaning is more likely.
