It should be noted that in previous wars, hiding in cellars or caves may help people escape, but it is different now. Because science and technology are very developed now, even if we hide in the deep mountains and forests, the enemy is likely to find people's hiding places through infrared sensing. Even if you dig three feet, you can't escape the heat induction. The development of science and technology is very useful in national security, but once war breaks out, it will only bring more serious consequences.
If you live in a city, it is recommended that you store grain for more than half a year, as well as oil and some medicines. In terms of food, you can prepare more staple foods, because staple foods are full and hungry. After the war broke out, there were bomb shelters and air defense alarms in most areas. After the air defense alarm sounds, you must hide in the air-raid shelter as soon as possible.
After the war broke out, the most important thing was to store food, and nothing else was important. Don't be greedy for money. After the outbreak of war, people's lives will not be as exquisite as before, so there is no need to carry some things. Everyone must give up. Only when we have prepared enough food can we successfully save our lives and help the country when it needs help. Because the current network is relatively developed, after the war broke out, we may also be able to learn about the war situation in many places online.
