With the sudden attack of the epidemic in Shanghai, many families ushered in a "closed life" before they had time to reserve materials, which made many families feel a little caught off guard at first. This situation may happen again in the future. What I'm sharing with you is an epidemic guide, not a panic. However, if it is really a special period, we must first give full confidence in the supply and distribution of national materials, but we must also have a sense of crisis and ensure reserves in advance. This time, the epidemic situation in Shanghai sounded the alarm for many people, because the imported strain of Omicron spread too fast, and Hua Ting Hotel, as a point of isolating hotels, spread very fast, and the speed of traffic adjustment could not keep up with the speed of spread. In terms of food, it can be preserved: canned products can be preserved for a long time, generally for more than 3 years as long as they are not broken or expanded, and canned products are completely isolated from the air. Canned food can also be further processed with other ingredients and become delicious after secondary processing. Staple food: a person can eat rice for several months according to the preparation of 50 kg. Rice will not go bad in a short time. If you are worried that the air is too humid or the rice takes a long time, you can put a few peppers in the rice and put the rice in a sealed storage box. Or put these things in clean empty bottles, which can be preserved for a long time without deterioration. Daily necessities: We must consider buying some household necessities. This time, someone found that there was no detergent, not even toilet paper. They can only rely on their good neighbors for emergency.
