The two-part allegorical saying behind a moth fighting a fire is suicide, which means that the moth fights a fire and then dies regardless of life and death. The first meaning is that some people bite off more than they can chew, and then they end up failing. The second meaning is to express praise for people's unswerving spirit of sacrifice for their own ideals and pursuits.

Moths put out the fire from "Biography of Liang Shu" to irrigation. "How can you set yourself on fire by grinding ink and writing letters and flying?" It's only one year, and you can still take a vacation. "

Extended data:

The scientific explanation for putting out moths and putting out fires is as follows:

Hundreds of millions of years ago, there was no artificial fire, and moths were guided by natural light sources such as sunlight, moonlight or starlight. Because the sun, moon and stars are far away from the earth, the light they emit can be considered as parallel straight lines when they shine on the earth. When a moth flies in a straight line, the angle between its forward direction and the light at any position is a fixed value.

In addition, if the light sources are very close, such as torches or candles, the light they emit can no longer be regarded as parallel light, and moths fly according to their inherent habits, and the flight path is not straight. It kept getting closer to the light source and finally died in the fire, that is, a moth threw herself into the fire.
