When the summer is not over, cutting the grain for the old cow means that when the summer is over, the millet will be confiscated without heading, just like useless weeds, which can only be cut for the cow to eat.

This agricultural proverb is about the season, the season waits for no man, and the climate waits for no man. If you miss it, you will not catch up. If the late-planted flower crops still don't blossom and ear before and after the summer heat, then this season's work will be in vain.

If millet doesn't have long ears in summer, it can only be plucked and fed to cattle, because even under the best conditions, millet can't grow, so it's better to pluck it. Therefore, due to various reasons, crops grow slowly in autumn, and farmers look forward to the ears in the fields every day, fearing that they will not see them in summer.

Introduction to summer heat:

It means "out of high temperature", which means out of high temperature. At this point, the dog days have passed or come to an end, and the summer heat in early autumn will also end. The bucket handle of the Big Dipper points southwest (position E). When the sun reaches the longitude 150, it is the summer heat in 24 solar terms.

Summer is a solar term reflecting climate change. Due to the short-term regenerative weather of "autumn tiger", it will still be very hot after the summer heat. Although it is not as hot as summer, it will still be muggy and dry. The arrival of the hot summer also means entering the second half of the dry calendar.
