What is the currency of the phoenix banknote?
Excuse me, could you please clarify for me what exactly is meant by the phrase "currency of the phoenix banknote"? Is it referring to a specific type of digital currency that is somehow tied to or represented by a phoenix-themed banknote? Or is it a more metaphorical way of describing a particular financial instrument or asset that carries a unique or symbolic value? I'm intrigued and would love to understand the context and meaning behind this term.
