The First Trader in the Song Dynasty

He was a minor official in Lin'an Prefecture in the Southern Song Dynasty. He was in debt of 800 yuan and his creditor blocked the door. When I was desperate, I found a pile of "waste paper" that no one wanted piled in the warehouse - it was depreciated salt. Three days later, I paid off the debt. A month later, the wealthy businessmen in Lin'an Prefecture were all asking, "Who is that little official?" Three months later, Qin Hui sent a message: "Sir, my master wants to see you." Song Gaozong asked me: "Ai Qing, can you teach the prince this thing?" I said: "Your Majesty, this is called 'finance'. If you learn it, the Song Dynasty will not be destroyed."
