Which of the following solar terms reflects the phenological phenomenon of natural organisms?

The main consideration is to be shocked.

In nature, those natural phenomena which are influenced by the environment (climate, hydrology, soil) and have an annual cycle belong to phenological phenomena. Sting is the third of the 24 solar terms. On March 5th and 6th, every year, when the sun reaches 345 degrees, it is "in a daze". Sting means that when the weather gets warmer, the spring thunder begins to sound, awakening the insects that are dormant and hibernating underground. This reflects the phenological phenomenon of natural organisms.
