This is a question of cost. The market price of a kilo of pork is about 13 yuan, and the side dishes are Chinese cabbage, leek, corn and mushrooms. Except for mushrooms, which are more expensive (fresh mushrooms are 5-1 catty in 6 yuan), others are about two yuan. A kilo of jiaozi is a bag, and the cost is calculated at the market price. If you don't work, it won't exceed 10 yuan (half a catty of pork, a catty of side dishes, flour seasoning, etc. ). The unified procurement of large enterprises is very low, there is no intermediate circulation link, and there is almost no labor in mechanized production (you will understand when you see the dumpling wrapper). With all kinds of circulation costs, the cost of a bag of pork in jiaozi will definitely not exceed four yuan. In fact, just pay attention to this problem.
