What do you mean, staying in summer must be a disaster year?

As the old saying goes, "If summer doesn't come out, it will be a disaster year", which means that if the summer solar term comes out first, the grain harvest will not be very good, which means that the grain production will be reduced. ?

It must be a bad year to stay in summer. This paper expounds the relationship between waiting for summer and waiting for summer, and there may be a sequential or overlapping relationship between them. If they conform to the summer heat, they will be superimposed on each other before the summer heat comes. According to the experience left by ancestors' observation, it is believed that the decrease of high temperature weather will affect the growth time of crops and the harvest of grain, resulting in the failure of autumn grain, which is definitely a disaster year.

The heat is not terrible, it must be a disaster year.

In the agricultural age, the skills of scientists were not developed. People depend on the weather to eat. Drought, flood or cold and warm weather often lead to a sharp drop in food production. People are worried that they will not be able to eat, so they often warn in advance, pay attention to the changes in solar terms, and remind people to make preparations in advance to ensure a bumper harvest.

In fact, even before the summer vacation, it's only five days at most. This year, just one day away, time is very short, fleeting. The impact on crop growth in such a short time can be ignored. Therefore, staying in summer is definitely a disaster, and it is not so terrible.
