Jingzhe, or Awakening of Insects, the third of 24 solar terms on the Chinese lunar calendar, begins on March 5 this year. In Chinese folklore, the year's first thunder, called "Spring Thunder", is believed to wake the insects.

In early spring when timely rain descends,
The thunder starts to rumble in the East.
From deep recess the animals are roused,
Both trees and herbs straightway with leaves increased.
--Tao Yuanming (Eastern Jin Dynasty)
