People who stayed in the countryside of the Taihang Mountains in the last century may have seen the plough of the cultivated land in the mountains, the plough of the cultivated land actually has two parts, the lower triangular hollow, installed on the wooden stake of the plough is called the plough corner, the upper part of the plough corner is called the inverted "8" gourd-shaped part called the wamphragm, the lower part is pointed, easy to insert into the soil, and the upper part allows more soil to be forced and increases the area of ploughed land. Some of them have walnut-sized "knots" on them, do you know why? When the elderly meet the children to ask the reason, they will tell the child this story so happily.
Plough the land forever
In the story 2 of Wang Lang chasing Liu Xiu, we talk about the old farmer who thought of a good idea in order to save Liu Xiu, let Liu Xiu lie in the ditch out of the plough, and then he was ploughed again, covered the soil on Liu Xiu's body, and covered Liu Xiu tightly, Wang Lang's pursuers came over and did not find Liu Xiu - Liu Xiu was buried in the soil in the ground, of course, they could not find it, nor did they think that Liu Xiu would be buried in the soil. This would have been a good idea to be in a hurry, but the old farmer did not consider that Liu Xiu was buried in the soil, could not breathe, and would be choked to death. At that time, the pursuing soldiers came, the situation was urgent, and there was no thought. When the pursuing soldiers could not find Liu Xiu in this field, they went to the neighborhood to look for it, but they still couldn't find it, so they left. The old farmer watched the pursuing soldiers go far, and saw that the place where Liu Xiu was buried was motionless, so he slapped his thigh, remembered, and shouted: "Bad things, this rush to save people, turned good things into bad things, buried in the soil for such a long time, can't change the gas, this is not that they did not save people,but also buried people alive!" "Hurry over and dig by hand." Liu Xiu swooped down and made it from the soil, and the people were well, and the old farmer was not light. What's going on? It is said that Liu Xiu is the true dragon Tianzi, and God helps him. In fact, it is not God who helps, it is the plough that helps.
It is said that the old peasant did not expect to bury Liu Xiu in the soil and die, so he buried Liu Xiu with the soil, Liu Xiu is a true dragon heavenly son, sent down by heaven to save the people, if he chokes to death, he will get it. The ploughman thought of this, and in a hurry, a lot of pimples appeared on the plough. These knots saved Liu Xiu. It turned out that with these knots, the soil that turned over became a piece of soil lumps, these soil knots buried Liu Xiu, there was a gap between the knots, Liu Xiu's nose was high, his nose looked like a knot, and he could breathe in the gap between the knots, and he couldn't find it, so the knots on the plough saved Liu Xiu, and didn't let him die in the soil.
Plough corner
Later, Liu Xiu met Cen Peng, Ma Wu, and others in the Taihang Mountains, moved to rescue the soldiers, led the people to lay the world, and sat on the emperor. In order to commemorate the life-saving of the knotty plough, some blacksmiths of the ploughs on the Taihang Mountain deliberately forged the knots to commemorate the rescue of the lumps of the ploughs!
Plough wrench (the pointed head is divided into plough horns, the upper part is a poop, and some of the pimples on the Taihang Mountains have knots, called "knots")
