During the Spring and Autumn Period and the Warring States Period, Qin swept the six countries, attacked Huns in the north and barbarians in the south, unified all countries and established the prestigious Daqin Empire. Then the problem is coming. Under the backward traffic environment in ancient times, Qin Jun started from Shaanxi, went to Lunan in the east, Hainan in the south and Liaoning in the north. How do hundreds of thousands of Qin Jun soldiers rely on expeditions again and again?

This is the dry food that is still loved by Shaanxi people-Guo Kui, which can be traced back to the Shang and Zhou Dynasties at the earliest. Zhou Wenwang was already military food when it was cut down. Guo Kui used wheat flour to make dough, fermented it, rolled it into a round cake, and slowly baked it in a pot. Even in summer, it will not go bad for a long time, similar to the compressed biscuits now.

Guo kui made by Qin people is big and thick. The diameter is about 50-60 cm and the thickness is about 15 cm. One weighs five or six pounds, and two holes are drilled in the helmet and tied with a rope. Two are the front chest and one is the back chest of a group of Qin Jun soldiers. The special handling method plays the role of armor. Since then, soldiers in Qin Jun have called this kind of rations "Guo Kui".

As an armor, Guo Kun is hard enough to resist bows and arrows, and it is bound to be difficult to chew when entering the mouth. So it is more convenient to eat with soup.

Chi broke the pot helmet into small pieces and put it in the hot beef mutton soup. Another delicacy, beef and mutton buns, comes from this. Qin Jun's food is even more fierce, and it swept the six countries bravely on the battlefield.
