Map of the Kingdom's Warfare.

Summary

Zhang Xuan presents a box of various copper coins to the ministers, highlighting the chaos in the Northern Sui's monetary system. He discusses the poor quality of certain coins, particularly the Daye rotten coin, and proposes minting new coins to replace the outdated ones. The ministers agree on the need for reform, leading to a unanimous vote to draft a new monetary law and mint new coins, named "Datong Tongbao."
