Heizi was as excited as if everyone was talking about him, whispering, "Brother Fei, Brother Fei, say a few more words!"
Yan Fei nodded, a simple action that immediately quietened the crowd around them.
Only his voice rang out, "Everyone knows the Three Knowledges and Six Cleanliness. The Three Knowledges are recognizing cold, hunger, and disease, while the Six Cleanliness simply means that in addition to providing clean feed and water, we also need to ensure the 'pen is dry, trough is clean, and the cow is disease-free'. Everyone, make sure to regularly clean the cowshed so it doesn't stink all the time. Prisoners' cells even get cleaned regularly! How would cows enjoy being surrounded by the smell of cow dung and urine all the time?"
Everyone responded with a round of laughter, but soon quieted down again to continue listening to his explanation.
