What do you mean, the villain is not full, light and cool in summer, and safe?

It means that there are still a few days before Xiaoman's season.

When the wheat is full, there is a risk: when the wheat is full, the wheat grains are reduced. The risk here refers to dry hot wind. The arrival of Xiaoman solar terms has also brought high temperature, but the temperature between days is still very different. Only such weather can help wheat to accumulate starch and realize milk ripening. If there is an unusually hot dry wind during this period, wheat will die in a large area, and it is impossible to carry out photosynthesis for starch filling.

Xiaoman, one of the "twenty-four solar terms", is the second solar term in summer. Xiaoman, battle nail, the sun reaches 60 degrees of the yellow meridian and is celebrated every year on May 20-22 of the Gregorian calendar.
