Superstitious theory of "reaching for water and rice"

"Pouring rice" is a folk superstition custom, which is common in backward and remote rural areas. The main method is not to see a doctor when you are sick, thinking that there is a mysterious force pestering you, that is, ghosts and the like. Put some boiled water in the bowl and some rice in the bowl. Standing in a bowl with three chopsticks, calling the patient's name: calling back his soul. Then throw the water and rice together. When sick people are released by ghosts, they will recover.

The way to pour water and rice: back down from your shoulders and don't look back.

Although this practice is foolish, it reflects the ignorance of human beings in the struggle with nature to some extent.

With the development of society and the improvement of people's scientific and cultural knowledge, this superstitious practice has basically disappeared and is only seen in the poor.

The shelf life of food should be scientifically formulated, but some manufacturers are arbitrary or rude. Most food hygiene departments have no mandatory shelf life, but as long as the factory is more formal, they dare not set the shelf life at will, because if the shelf life is too long, the food may deteriorate during the shelf life and the factory will be punished. The shelf life is an artificial date, and harmful substances such as bacteria will not grow and reproduce during the shelf life. Generally speaking, the longer the food is stored, the greater the harm to people and the lower the nutrition. The storage conditions of food during the shelf life also have a great influence on the deterioration of food. For example, if a cake is wrapped in plastic paper and sold in the sun, it will go bad easily, but if it is sold in the refrigerator, it can be preserved for a long time. Legally speaking, people can claim compensation for eating within the shelf life (it should mean eating immediately after folding), but if they eat beyond the shelf life because of consumers' storage, they can't get compensation. Theoretically speaking, food beyond its shelf life should not be eaten any more. This can be said to be a common occurrence. Food beyond its shelf life can never be sold again. There is no law on whether the food beyond the shelf life is absolutely inedible. You can judge for yourself according to the above contents.

There are new regulations on the shelf life of food.

Not long ago, the State Light Industry Bureau made new provisions on the shelf life of food, and the specific time limit is as follows:

Milk powder: canned for 12 months; 9 months in a glass bottle; 500g plastic bag for 4 months; Tinplate canned sweet condensed milk is 9 months; Sweet condensed milk in glass bottles is 3 months old.

Malt milk essence: canned tin cans are
