The foolish person sacrifices sweet sleep and eats cold fritters. They give milk to strangers, only to find their own flour has become moldy.

This couplet vividly describes a foolish person who consistently prioritizes others over themselves. They lose their precious sleep, signifying mental peace and rest, and end up with cold, stale food, indicating a lack of basic comfort. The core message is in the second line: they generously offer milk, a symbol of nourishment and value, to strangers, while bringing home something as worthless and unpleasant as 'stinky flour' for their own consumption. It's a poignant portrayal of someone who sacrifices their own well-being, comfort, and resources for others, only to be left with hardship and neglect for themselves. It warns against excessive selflessness that leads to personal detriment.
