One day, a man suddenly created a disturbance, claiming he had vomited and had diarrhea after drinking milk from Qin Ming's farm. He accused them of selling old milk, asserting the milk was leftover from the previous day and had spoiled, and accused them of making unscrupulous profits.
However, Qin Ming repeatedly assured that their milk was fresh, produced on the same day. If there was any unsold milk left, they would mix it with fodder for the cows to consume, never selling it to the villagers.
So, the man who fell ill argued, "If it's not the milk, then it must be the cows. They must be diseased or unclean. You are risking the villagers' lives for profit. The breeding farm should be shut down immediately!"
But since this incident of vomiting and diarrhea from drinking milk only happened to him, the villagers didn't believe his accusations.
