In the folk song "Take the Native Produce" in Shanxi, the first sentence is "Piece of Taiyao's Beef Taigu". When passengers walk into the ancient Pingyao City, the Pingyao beef distributor who is good at business, always cut off one piece and try to attract customers with a taste of it. Because they know the psychology of the guests, they also know that the taste of beef will make guests satisfaction. Interestingly, the beef that has just been out of the pot, the knife is not savoury, and as long as the knife is pulled, the rich meat will suddenly come out, making people feel bitter and sullen.
