to wake up the sleeping taste buds and help each other with food means to be in the same predicament and help each other. According to the relevant public information, caring for each other means that people in the same trouble can support each other, give strength and even maintain each other's lives. Its original meaning means that two fish are fished out of the water. Because there is no water, they spit on each other to keep each other wet so as to live. Nowadays, it is often used to describe the feelings between husband and wife that depend on each other and never give up. This idiom originated from "The Great Master of Zhuangzi": "When the spring dries up, the fish phase is on the land, and it is better to forget each other in the rivers and lakes."
