Your account is not easy to calculate. You can directly buy 13 yuan, 6 kg of noodles. This is a one-time thing. Next time I buy 13 yuan, I need 6 Jin of noodles. You spend 600 yuan on a manual noodle machine, you can't just use it once. It can be used many times, maybe for many years, so this flour is one yuan and eight Jin. You made it yourself. Don't worry. This noodle tastes safe. Nothing was added. Noodles bought outside are not necessarily safe. People may have mixed something else in it.
