Are Liu Bowen's disciples selling knives?

According to anecdotal reports, those who pay for knives on credit are descendants of Guiguzi, a famous historical figure and founder of strategists in the Warring States Period. Proficient in the art of war and divination strategy, he was praised as "seeking holiness" by later generations. Guiguzi founded Guiguzi School, leaving a book, which was banned by successive dynasties and called "the wisdom of forbidden country, a wonderful book" by later generations.

As the name implies, people who borrow knives on credit only sell knives. The knives they carry are scissors, kitchen knives, hoes, sickles and other knives commonly used in ancient people's production and life, and even some daily necessities and farm tools. However, the trading style of credit for knife holders is very unique. They give people knives on credit, and then leave a few words or a prophecy, which is often a prophecy. If the prediction comes true, they will come back to get back the goods that have been sold on credit and charge a commission.
