What does the old saying in the countryside mean, "Carpenters don't trim their edges, butchers don't kill pigs with five claws"?

As the saying goes? Vulgar? But they all contain wisdom, just like the saying in this topic? Carpenters don't trim edges, butchers don't kill pigs? Now it seems that there is still some truth. However, after all, this proverb was summed up by the ancients according to the life experience and conditions at that time. Today's living conditions and modern people's ideas are definitely different from those of the ancients. Therefore, to judge the truth of this proverb, we must analyze it from ancient and modern aspects respectively, so as to draw a more objective conclusion.

Carpenters don't trim edges, butchers don't kill pigs? The literal meaning of this proverb is not difficult to understand. It means that carpenters don't want to do carpentry with just the right size wood, and butchers don't kill pigs with five claws. After understanding the literal meaning of this proverb, we will verify the correctness of this proverb from the ancient and modern perspectives respectively.

In ancient times, this proverb was completely correct. Let's look at the first half first. Carpenters don't trim edges? Here? Dressing materials? Of wood of the right size. We all know that carpentry is a delicate job, and carpenters will carefully measure it with various measuring tools when doing carpentry, but then again, even careful people will make mistakes. If the size of the wood provided by the employer is just right, then if the woodworker makes a little mistake or the wood quality is problematic, the task will fail.

On the other hand, errors are inevitable, even for the most sophisticated instruments. It is impossible for a carpenter to completely meet the pre-calculated results in actual operation, and there will be some errors, so if the size of wood is just right, there is no room for errors, so it is difficult for a carpenter to complete the task perfectly, so it is reasonable for a carpenter not to trim the edges.

Look at the second half of the sentence? Butchers don't kill pigs with five claws? A five-claw pig refers to a pig with five claws. Under normal circumstances, pig's trotters have only four claws, and pigs with five claws are rare. The ancients were superstitious. They think that pigs with five claws can't be killed and must be released, otherwise it will bring bad luck and so on. So what? Butchers don't kill pigs with five claws? It is completely understandable and correct to put it in ancient times.

In modern times, this sentence is only half right. The first half of this proverb? Woodworking doesn't trim? It is also correct in modern times. Although today's woodworking tools are more advanced and accurate than in ancient times, as long as they are handmade, mistakes will inevitably occur, so even modern carpenters are unwilling to accept carpentry with just the right size of wood.

The second half of this proverb? Butchers don't kill pigs with five claws? In modern times, it is unscientific and objective. From the perspective of modern science? Five-claw pig? This is only a question of probability, not superstition, so there is no such thing as the consequences of killing pigs with five claws. Of course, God has the virtue of living well, and killing is always bad, so it is better not to kill.

This topic once again illustrates the importance of historical situations, and the correctness of proverbs should be analyzed from different historical situations. Sure, but all proverbs should be interpreted from more than one angle. These are just some of my opinions, which may not be accurate. Please correct me if there are any mistakes or omissions.
