Original text:

Niu Geng's 1,000-acre disease has brought the fruits of labor to thousands of granaries, but its own spirit is very tired and exhausted, but who will pity its hard work?

But in order to satisfy all sentient beings, even if they are sick in the sun, they will not hesitate.

The sick and wounded inside are still working hard, and they have written the quality of hard work and work in spite of illness.
