As early as the civil war in Japan and the war in the southwest, the Japanese army began to equip a large number of canned meat products. At that time, there were two kinds of purchasing channels, one was domestic, and the other was imported from the United States. Although the canned beef imported from the United States was beautiful and had sufficient weight, it was imported until the Russo-Japanese War, but generally speaking. Soldiers of the Japanese Army didn't like American tastes, and they were mainly made in China in the later period.

As the Japanese invading army gradually fell into the quagmire of the war of aggression against China and the Pacific War, the domestic economic situation became worse and worse, and the war resources that could be used became less and less. At the beginning, this kind of things that tasted good began to be shoddy. At the end of the war, the ingredients contained in it changed from beef and vegetables to cow's blood and cow's water. Even turned into bran and rice bran, and became a rotten ball.

isn't this what pigs eat in the eyes of most Japanese? With the advance of the war, Japan's national strength is getting weaker and weaker, and it is these things that are not good to eat and not good to look at that piece of canned veal. Putting them in your mouth is particularly uncomfortable and stinky, which is even worse than pig food. Many Japanese materials were intercepted during the Anti-Japanese War. China people also tasted each other's feelings, and knew the food of the Japanese army.

It is precisely because Japanese food is getting worse and worse that ordinary Japanese soldiers like to use local materials. In addition to attacking the enemy, there is also an important task in every sweep, that is, robbing local people of chickens, ducks, pigs, cows and sheep to improve their food, regardless of the lives of local people, which makes people feel a little angry. But after all, there is nothing they can do. If they can't eat well, they must find some ways to solve the problem of food and clothing.
