What do you mean, there are no plowed fields, only exhausted cows?

There is no arable land, only exhausted cows, which means that arable land can be cultivated all the time, and cows can't work endlessly.

Now alluding to the way between men and women. Cattle will be tired and thin if they don't plow for a long time. When Niu Gengdi came, cows became stronger and the land became more fertile. However, if there are too many Niu Gengdi, the cattle will become thinner and thinner, and the land will be over-nourished. So start with your needs. You know, the land is always there, and the fear is that there are no cows to plow. So the health of cattle is very important. Think before plowing, is the cow in good health? Whether you are still full of energy or not, you should also consider whether your recovery ability after Niu Gengdi is ok. Lying there quietly, the cows are desperately plowing the fields, so the cows are exhausted and the fields are not bad.

Tell people to know how to do things and how to work hard. To extend it: it is shameful to idle or waste resources for too long; It is important to grasp the degree, and rational allocation and utilization is the best.
