1. Sufficient quantity. Although the ration of each meal in the army is very small, it is enough to join the collective supply. You can eat well, but you don't have to eat well.
2. Repeat the cycle. The meals of the troops are mainly coarse grains, and the dishes are single, but they are repeatedly supplied at regular intervals. Repetition for a long time won't produce too much boredom, so I feel richer.
3. Eat together. The troops have a collective meal, and everyone eats the same food together, which creates an atmosphere and interaction of sharing meals, and also strengthens the illusion of rich food. We can discuss today's food together and make a joke to make the food less monotonous.
4. More quantitative. Although the food in the army is not delicious, if everyone is given a ration, the most basic nutritional needs can be met. Don't worry about being hungry or eating very little at a meal, which also makes people feel richer.
5. Don't have high expectations. The requirements and expectations of the officers and men of the army for food are relatively low, mainly to eat enough. There is not much demand for the pursuit or choice of food. Therefore, any food that exceeds the low requirements will feel very rich.
To sum up, the army can eat more abundantly under low standard conditions, mainly because of sufficient quantity, long repetition period, good dining atmosphere, ensuring basic nutrition and low requirements. Everyone eats the same food collectively, without high expectations, so any food will not feel too scarce and produce rich impressions. This is in stark contrast to the society's pursuit of a variety of foods. Generally speaking, enriching this feeling is subjective.
In life, we can appropriately reduce the requirements for material life, cultivate a good attitude and atmosphere, and life will feel much richer. This is a place worth learning.
