The purchase price is cheap. The large collection of Linshu grass frogs at the foot of Yimeng Mountain has a long history. This big collection is very famous in the local area, and many people come back from afar to go to the market. The collection is bustling and crowded. The food in the big collection is very fresh and cheap. The stall was just picked from the ground. Spinach is green and shiny, and it costs only one yuan a catty, which makes the city people envy it. In addition to vegetables, there is also ultra-low-priced pig's head meat, which is very cheap at eight yuan a catty. Because there are many people in the market and many people buy it, the uncle who sells pig's head meat says that pork is really worthless now and the purchase price is very cheap, so pig's head meat is also cheap.
