The pork in the morning is not fresh, and the tofu in the evening is left. The reason for not buying tofu late. Tofu is usually cooked in the morning, and craftsmen grind beans early to make tofu. Generally, you can eat tofu for breakfast, which is more popular with people. With the progress and development of modern science and technology, tofu is generally made by machines. After soybeans are made into watercress, they are put into a professional machine and ground into slurry with water. After the pulp is made, find a clean cloth and two sticks, a rope and a big basin, and then assemble them to filter the bean dregs and soybean milk. Pour the soybean milk and bean dregs into the cloth and filter, shaking constantly on the way to let the soybean milk flow into the big basin. This is the process of shaking, which requires two people to operate. After the soybean milk is filtered out, it is heated in a plastic bucket. After heating to boiling, take out the soybean milk and make tofu. Then put a special wooden frame for making tofu on the table and put some straw under it. Put a clean cloth on the tofu rack, and then pour the tofu flower into the rack. Cover the tofu with the wooden cover of the tofu rack, and then press it with a big stone. This is mainly to squeeze out the excess water in tofu and turn it into tofu. Eating tofu at night will lose nutrition, so don't buy tofu at night.

Reasons for not buying pork earlier. Generally, few people get up in the morning to kill pigs and go to the market to sell pork. Most people kill pigs in the morning or at noon to sell pork. If it is pork in the morning, it is usually left over from the day before, which is not fresh and may even be corrupt. Such pork people will not be healthy if they eat it. So it is not recommended that you buy pork in the morning. It is best to buy pork at noon, so that someone can sell fresh meat instead of the day before. Who doesn't like such pork?
