In the year when the First Emperor of Qin burned books, I stole half of the "Kao Gong Ji"; when Emperor Gaozu of the Han Dynasty took credit, I wrote down the IOUs from all his princes; on the night before Empress Lu killed Han Xin, I took away his sword. Eighty years later, Emperor Wu of the Han Dynasty asked me whether I should sell salt and iron exclusively - I said that I had already written the answer in a book.
