The time of thunder in northern spring

From mid-March to early April, there will be thunder in the spring in the north.

Spring thunder is usually after the sting, and it means that spring has come, usually from mid-March to early April.

Sting is the first thunder of spring. The so-called "spring thunder". In the dormant season, spring thunder began to sound, and hibernating insects were awakened by thunder and broke out one after another. One year (year) and twelve months, each month corresponds to a divination, and the Uzuki (including the two solar terms of fright and vernal equinox) corresponds to a thundering divination.
