越南古称安南，自公元９７０年以来，一直仿造中国方孔钱铸行货币。由于安南铸行的货币多形制薄弱，质量不佳，人们更乐于使用质量优良的中国古钱，再加上明清以来两国贸易的繁荣昌盛，从而大量的中国古钱流入了越南。这也是如今越南境内经常出土中国古钱的原因。我新近从广西 Annan, the ancient name of Vietnam, since AD ​​970, has been imitation of China Fangqian money cast line currency. Due to the weak currency and poor quality of Annan’s casting line, people are more willing to use the ancient Chinese money of good quality.
