What are the characteristics of the director "threshing floor" in the paper?

In the hot summer, the director of the threshing floor is a figure who rarely appears, is not good at words and does not show much.

In this article, the director of the threshing floor is surnamed Su, who is from Shandong. For a year, it seems that there is no such person as him. But he was particularly arrogant at the moment when he grabbed the field in summer. He can smell the wind rising at the end of qingping, and he can cover the wheat straw before the rain comes.

As soon as the rain passed, he would knock on the broken track board of the tractor hanging on the threshing floor, shaking the earth, commanding everyone to seize the time and quickly lift the tarpaulin and straw curtain covering the wheat to dry. I don't know how many times this tarpaulin has been lifted in one day. It's a race against time.

In the summer solar terms, only wheat is big at the juncture of grabbing fields. I was really afraid of rain. Unlike now, before and after the summer heat, the summer heat has not completely dissipated, so I am looking forward to some rain to cool the weather and add some poetry.
