There are a large number of organisms with soil fertility, and the limit that human resources can reach is very large. If you take it in moderation and use it in moderation, you will always be satisfied. Take it too much, use it too much, and it is often insufficient.
At noon in summer, the sun is very hot, farmers are still working, and beads are dripping into the soil. Who knows that every meal in our plate is obtained after hard work?
Cherish food and your children and grandchildren will be blessed.
Don't forget the famine when the grain is stored.
There is not a wood, not a grain of rice.
That's all.
