What does it mean for a little man to move three cars?

Xiaoman has three cars, a waterwheel, an oil truck and a silk truck.

After the solar term, the temperature will rise further. At this time, the crops in the farmland need water most, so if there is little rainfall, the farmland should be irrigated in time. In the past, irrigation in rural areas was not as easy as it is today. It uses a water wheel, which is trampled by human power, and then sends the water below to the farmland above. Oil tanker, in the south, rape will also start harvesting in Xiaoman solar term. After harvesting rapeseed, it needs to be dried in the ground for a few days and then beaten in time. Then, after drying camellia oleifera seeds, it can be dragged to the oil mill to squeeze into fragrant rapeseed oil, so this requires an oil truck. Silk carts, in ancient times, farmers in the south of the Yangtze River not only could not delay farm work, but also raised silkworms in many families. At this time, the silkworm has grown up and is about to start cocoon formation. Therefore, for sericulture families, it is necessary to start reeling with a silk cart. In the past, many people in the south raised silkworms, and farmers also raised silkworms when they were young. Watching them grow up bit by bit is also a great sense of accomplishment. But now in the countryside, not only adults don't keep silkworms, but also children can't see them.
