How to use literal metaphor to describe uncooked rice?

As an idiom, "raw rice" refers to uncooked rice. Metaphor is not completely finished.

Zhou Enlai's "Telegraph to Fuping Central Bureau on Land Reform and Party Consolidation": "Anyone who wants to complete such a detailed land reform work by one force, at most, is like cooking raw rice in Northeast China and cooking it again, otherwise it will be wrong and corrected."

The custom of raw rice

Yeche people who live on Ailao Mountain usually hold weddings at dusk. When the bride is received by her husband's family, she will eat "raw rice" in addition to the custom. This kind of uncooked rice must be steamed until it is seven minutes cooked, so that it can be considered as external cooked and endogenous. Yeche people think it is a good sign that the bride eats raw rice.

Interesting explanation:

It looks cooked and eaten raw, but it's actually a little cooked. It's a very contradictory meal!
