It's from Li Shen, a poet in the Tang Dynasty. The original poem is a millet planted in spring and ten thousand seeds harvested in autumn. Under heaven there is no waste of heaven and earth, and the labouring peasants are still starved to death.

As long as you sow a seed in spring, you can harvest a lot of food in autumn. All over the world, there are no fields that are left uncultivated and uncultivated, but there are still working farmers who starve to death. At noon in midsummer, the scorching sun, farmers are still working, sweat dripping into the soil. Who would have thought that the rice in our bowl is full of the blood and sweat of farmers?

note: compassion: pity. There is sympathy here. One poem is Two Antique Poems. The order of these two poems is different from version to version. Millet: generally refers to cereals. Autumn Harvest: A "Qiu Cheng". Son: refers to grain particles. Four seas: refers to the whole country. Idle field: A field that is not cultivated. Y: Still. Grass: a general term for cereal plants. Meal: a "meal". A generic term for cooked food.
