There is a story in "Notes on the Qing Dynasty", in which a noble man was cheated by his chef and took bean sprouts as a luxury. One day, a nobleman went to visit his relatives because they borrowed money from him. When eating, he saw bean sprouts on the table and asked the relative: You always say you are poor, so why do you use such extravagant things for dinner? This is what I usually use, one hundred and twenty taels of silver per plate. Relatives told him that bean sprouts are cheap, but in fact they only cost two or three pence. The nobleman came home and asked the chef. The cook cut off the bean sprouts, covered them with shredded peppers and added sesame oil and soy sauce. He said that three pence is too expensive for the poor to eat with salted bean sprouts, and the bean sprouts that shopkeepers eat on weekdays are really expensive. Therefore, it deceived the nobility.
