The second half of the sentence "Hungry and cold began to steal my heart" is the crowning touch of the whole sentence. Let's start with the simple meaning of "food, clothing, lust". If a person is materially rich and sufficient, and he can never worry about his life, then he will be idle all day.

It is easy to have the idea of harming others and not benefiting themselves. This is closely related to our real life. We work hard for our studies, career and house all day, just to have a stable and rich family! If you suddenly become rich and don't have to think about work, mortgage repayment, promotion and the future of your children all day, will you still choose to work tirelessly? No, you'll get caught up in pleasure and you won't get out.

It comes from the ancient children's enlightenment reading "Augmented Sage":

The wisdom of the ancients is far beyond our imagination, which is closely related to the influence of our traditional culture since childhood. If we want to study these two simple sentences, it is consistent with Maslow's demand theory.
