According to some data I found on the Internet, Mala Tang has a high profit margin. As we all know, vegetables, for example, are 1 kg, which is about 30-50 trees in 0.8 yuan. If you sell five oil wheat dishes and baby dishes in a string, you can sell 3-5 pieces, and a piece of instant noodles, 0.3 yuan, sells 1 piece.

If calculated according to the price of a catty in 25 yuan, then a catty of mala Tang Tang Can sells 50 strings or 25 instant noodles, and the total income is 25 yuan. Assuming that the cost of each string or instant noodle is 0.4 yuan, the total cost per catty of mala Tang is 20 yuan. Then Mala Tang's net profit per catty is 5 yuan, with a profit rate of 20%.

Of course, this is only a simple estimate, and the actual situation may be different. You also need to consider other operating costs, such as rent, utilities, labor, etc. In addition, you can increase your income and profit by improving quality, service and marketing.
