A Chinese underground banking system, the term itself meaning literally "flying money". It is based on trust, family ties, local social structures, and the threat of ostracism for any breach of good faith. This system generally involves depositing money in one country in exchange for a "chit" or "chop" (seal), and the remittance of this money in another country on presentation of the chit.
