There is a saying in the northeast called "Don't take steamed bread as dry food". What are the meanings and allusions?

Don't treat the village head as an improper cadre, which means that the village head's official is very small, but he is also an official.

Because rice was the best staple food in the past, and the poor ate coarse grains such as steamed bread, steamed bread was not delicious, but it was also dry food (staple food).

Haha, the culture is not high, I don't know if I can express it clearly.
