Self-driving trip to Yejiazhuang, Laiyang, Shandong.

Driving in Shandong along National Highway 204, the scenery is right on the roadside. As the sun sets, you can see endless farmland, the corn has been harvested, and some fields have begun to be plowed. There were no farmers in the fields, only a tillage machine plowing the land back and forth. For a piece of farmland of about 5 mu, the tillage machine only went back and forth five or six times, and it took 10 minutes to plow up the oily black soil. I was thinking: if the farmer used oxen to plow the land, it would probably take a whole day, right? No wonder there are no farmers in the fields! At this time, the setting sun had turned red, dyeing the clouds in the sky red.
