"Painting cakes to satisfy hunger" is a metaphor, which means taking it for granted that things that don't exist can solve practical problems. This sentence conveys a philosophical truth, that is, don't just stay at the level of imagination and ideals, but face realistic problems. Only down-to-earth efforts and practice can truly solve practical problems, rather than fantasy and fiction. Therefore, this metaphor is often used to criticize those who only talk empty words and have no practical actions.

This metaphor can also be extended to other aspects, such as business, management, politics, society and other fields. In the commercial field, some entrepreneurs may rely too much on investment and financing, while ignoring practical problems such as product research and development and marketing. Such behavior is to draw cakes to satisfy hunger. In the political field, some politicians may put forward unrealistic slogans and policies, but they don't care about solving practical problems. Such behavior is also painting cakes to satisfy hunger. In a word, this metaphor reminds us to cherish and attach importance to reality, and we can't just stay in illusory imagination and ideals, otherwise haste makes waste, and the loss outweighs the gain.
