What farm tools did farmers buy in Han Dynasty?

The agricultural tools used by farmers in the Han dynasty were mainly made of iron and wood, such as thunder, which was actually primitive? Lei's farm tools rank first among the wooden farm tools in Shuo Wen Jie Zi, and each farm tool has a very unique function? Shuo Wen Jie Zi also lists all kinds of wooden farm tools, including those used for hoeing. Plough? Rake? Harvest? Farm tools like threshing?

Did the iron farmers in Han Dynasty have shovels? A pickaxe? Plough? Double-toothed hoe? Gardening hoe? Sickle and sickle, etc? There are at least four kinds of shovels, each with a specific name?

The evolution of plough shows that the change of farm tools is determined by their special functions? The prototype of the plow is just a kind of larger lei? When the thunder has a blade that can penetrate the soil, it actually becomes a plow? Will the sharp blade gradually develop into a more effective plough share? The back ridge eventually developed into a plow board, which also helped to turn over the soil?

At this time, the plow is too big for people to pull. Do you want to use cows or horses? However, the completely wooden plow could not adapt to the pulling force of livestock, so there was a major improvement, that is, an iron piece was added to the plow share?

Isn't the shape of the Han plough exactly the same? Some plows are so small that it seems impossible to pull them with animals? Large plows are very useful in plowing land? Medium-sized plows should be light, and two people can pull them, which conforms to the description of those light farm tools when Zhao promoted the farmland substitution method?

The use of plows became popular in the Han Dynasty, especially in remote areas, where local officials encouraged people to adopt Niu Geng? Iron officials who engaged in monopoly at that time, because of their functions, may regard the manufacture of iron plows as a shortcut to complete their rated tasks, and the manufacture and sale of plows by the imperial court may have promoted its use?
