How were the ancient poems about cherishing food written?

1, the first farmer, Tang Dynasty: Shen Li Chuntian planted a millet and harvested 10,000 seeds in autumn. There is no waste of heaven and earth, and the toiling peasants are still starving to death. Interpretation: As long as you sow a seed in spring, you can harvest a lot of food in autumn. In all parts of the world, no field is uncultivated and uncultivated, and hard-working farmers will still starve to death.

2. The Second Farmer, Tang Dynasty: Li Shen, weeding at noon, sweating like a pig. Who would have thought that our bowl of rice and grain are full of the blood and sweat of farmers? Interpretation: At noon in midsummer, under the scorching sun, farmers are still working and sweat is dripping in the soil. Who would have thought that the rice in our bowl was full of the blood and sweat of farmers?

3, "Farmer" Song Dynasty: Yang Wanli, rice clouds are not rainy or yellow, buckwheat flowers are early frost. It's worse than a leap year.
