Two thousand years ago, the delicious dry food necessary for war was what we called Guo Kui. At that time, the soldiers of Qin were fighting, and their dry food was Guo Kui, which was the most common dry food in the army at that time and also the favorite dry food of soldiers.

We know that it is very important for ancient troops to March and fight. If there is no food and grass supply, then this army can't fight well. Soldiers can't win a battle on an empty stomach. So the choice of dry food is very important. Our ancient and wise ancestors invented the pot helmet, which is convenient to carry, suitable for storage and delicious as dry food for war.

The advantage of the pot helmet is that it can be carried with you, and it is very big and can be carried on your back. So the origin of Guo Kun is because he is like the second armor worn by soldiers. Guo kui can also protect the lives of soldiers at critical times. Sometimes arrows fly on Guo kui instead of shooting at them directly.

Guo Kun is actually a very thick school. Guo kui's practice is also very simple. After the noodles are alive, they are spread out in the shape of big cakes and baked on the surface of the pot. It must be baked slowly with low fire until its moisture is basically clean. Therefore, the kettle helmet is very dry and easy to store, and the dried kettle helmet is hard and can be used to resist enemy attacks. It is really a good tool that can be eaten and saved. When Qin Jun marched into Qin Jun, Guo Kui provided him with many conveniences.

First of all, each pot helmet weighs five or six pounds, and everyone can send one a day. Moreover, they will carry a pot helmet on their backs to resist the enemy's attacks, which can also play a great role in the battle. So we have to admire the wisdom of our ancestors. Guo Kui has been preserved by us. It is a traditional food in our country. Many people will cook this dish at friends' homes in the north. Well, it seems to me that this is a delicious food that we should keep.
