Banking theory

Emperor Wen of the Western Han Dynasty was a court eunuch.

At that time, Xiongnu's famous modu chanyu died of illness, and his son stood in porridge, named Lao Khan. In view of the unstable domestic situation, Emperor Wendi coveted the throne with various governors, and his national strength has not been restored, so he was unable to fight a protracted war with the powerful Xiongnu. So he had to continue to kiss Xiongnu, and Emperor Wen ordered the imperial girls to go to Xiongnu, and let eunuchs go as accompanying courtiers. Bank of China refused to go and was dispatched by Han Ting. In anger, he said to Wendi, "If I go to Xiongnu, I will definitely threaten the Han State." Wendi Deng just felt that he was angry and didn't care. Unexpectedly, as soon as the Bank of China mentioned the Huns, it immediately surrendered, which won the joy and favor of the old Khan. The theory of the Bank of China tried to persuade Huns not to pay too much attention to the exquisite costumes and diets of the Han Dynasty, to increase their confidence in their own diets, equipment and customs, and to teach Huns how to count, so that these barbarians could know how to count. Encouraged by the theory of the Bank of China, Lao Shangshan was arrogant when replying to Wendy's book. He also bullied and lured the envoys of the Han Dynasty, demanding money, food, gold and silver at every turn, and threatened to trample on the territory of the Han Dynasty after the autumn harvest.
