What does the name of a frightened crow mean?

The frightened crows crow, the land dries up at the vernal equinox, and the sun divides day and night at the vernal equinox. Exposure time is prolonged, temperature is raised, and everything is revived. The growth rate of various plants in the field is accelerating, and the demand for water is increasing. In addition, with the increase of ground temperature, transpiration also reduces the water in the field. However, this solar term is rainy and windy, so there is a saying that "spring rain is as expensive as oil", and "drip drying" means that the demand for land water cannot be met.
