  #Person2#: Good morning. I have a Bill of Exchange against Bank Acceptance here. I'd like to discount it. Is that possible here?
  #Person1#: Yes, we can do that. We require the original Trading Contract and also the VAT Invoice and the Commodity Delivery Documents. They all need to be in duplicate.
  #Person2#: Yes, I've got all that here.
  #Person1#: Do you have a copy of the ID card of the person who took care of the legal aspects of this? The Legal Rep, I mean? We also need the Loan Certificate as well. Do you have that?
  #Person2#: A copy or the original? I guess you need the original, right? OK, I'll return shortly.
