What does it mean to thunder in the first month?

Thunder in the first month is a thief.

Lightning has incredible power in nature. Since ancient times, Han people have been puzzled and afraid of lightning. Especially in the period when there should be no lightning, there is lightning, which is considered as a sign of disaster. In Fangcheng, Henan Province, there is a saying: "In the first month, there will be thunder in the soil grain pile, in February, there will be thunder in the dung grain pile, and in March, there will be thunder in the wheat grain pile." Tugudui, that is, the epidemic has come and the graves have proliferated. October has entered the early winter, so there should be no more thunder, so there is also a saying among the people that lightning protection will take place in October. For example, there is a cloud in Hebei that says "When it thunders in October, the ghost king can't be idle" and "When it thunders in October, people will push it with a rake when they die". It means that there will be lightning in October and disaster next year. In Jiangsu area, there is also a saying that "thunder in October, the human body is mixed", which has the same meaning.
