Sending coins to Liao and Xixia D. Suppressing the peasant uprising I chose option A and chose option D. I don't understand. Don't you need money to suppress the peasant uprising? In addition, why would land acquisition lead to financial difficulties? Before Wang Anshi's reform, he used the two-tax law. He collected taxes according to assets and land.
