What do you mean, "Carpenters don't trim edges, butchers don't kill pigs with five claws"?

The meaning of this sentence is that we should leave a way out for ourselves in everything and act according to industry rules.

The ancient culture of China is profound and complicated. Agriculture, handicrafts, architecture and cultural industries all have their own trade rules. With more and more comprehensive knowledge and accumulated experience, many technical terms have been handed down as proverbs, and these proverbs are usually easy to understand.

This is the principle that carpenters should follow when they work. It means that carpenters should cut more when cutting, and can't cut according to the original size, because the wood is likely to be shorter when woodworking is over. After all, the drawing or design style will be different from the actual work. At this time, if the wood is long, you can cut some at will, but if it is short, there is no way out, and unlike rope, all previous efforts are in vain, and everything is in vain. Therefore, we should leave room for ourselves from the beginning and be prepared for the accident.

Butchers don't kill pigs with five claws, which means that everything should be done according to industry rules, which is what we usually call industry conscience. The pig that can be seen every day has four claws, which determines its future fate from the moment it is born. The master is very happy to watch it eat, drink and sleep every day. Five-claw pigs are rare in daily life, because they are ugly ducklings, deformed pigs and have poor life experience, so the butcher stipulates not to kill five-claw pigs.

Although these two proverbs were originally used in specific industries, the truth contained in them can penetrate into all aspects of life. A carpenter who doesn't trim is equivalent to taking precautions. The future without planning will only make people in a hurry, and it is even very likely that they will miss the opportunity. Industry conscience is also something that every industry should abide by. Be honest in life. Only by observing the reputation and doing things according to the industry rules can we get more benefits.
