In the silent summer night of the southern countryside, most farmers have already turned off. Occasionally, one or two fireflies flew to the window, and the flashing fireflies added a few more agile to the dull summer night.
Why does the fireflies shine? Simply put, it is a series of complex biochemical reactions that occur under the catalysis, and light is the energy released in this process. It is the unique light of fireflies that make it an important ornamental insect.
In Chinese insect culture, fireflies are named with butterflies. This little creature, I do not know the inspiration and love of how many poets of ancient and modern poets, and became the darling of the literati.

The word "stream" shows the spirit and lightness of the fireflies vividly. To this day, fireflies still often appear in popular songs. Their romantic figures and shining short lives have entrusted people with too many thoughts.

Once upon a time, Xia Ye accidentally stepped through a piece of grass, and a large amount of fireflies flooded out and danced in the dark. Unconsciously, they are slowly disappearing.
