A carpenter doesn't make a flush, a butcher doesn't kill a five-clawed pig.

The flush material? is just the right amount of material to use,? The five-clawed pig? is a pig with five hooves. The literal interpretation of this saying is that a professional carpenter would not use just choose just the right length of wood, and a butcher would not kill a pig if he saw that it had five hooves.

In the past, carpenters and butchers also belonged to the craftsmen, and people respected these two types of professions. Carpentry is a very detailed and specialized job. When choosing wood, they usually don't choose just the right length, but leave it a few centimeters longer.

This way there is still room for remedying the situation in case there are any surprises halfway through the process. At the end of the day, if it's too long, you just need to saw it off, but if it's too short, it's not so easy to remedy.

This is the main reason why carpenters don't choose just the right length. A carpenter's reputation has been important in the past, and it would be a loss if he smashed his reputation over this little problem.

Pigs generally have four hooves, but some pigs are strange and just happen to have five hooves. Butchers who see a pig with five hooves usually won't do it, and people in the past thought it was ? Five-clawed Golden Dragon? The pig is a very noble thing. It was something very honorable and rare.

People put ? Five-clawed Golden Dragon? as if they were holy objects, how could they still lay their hands on them and kill them? Once they have done so, they will be punished by the heavens. The second half of this sentence is naturally still with a certain superstition, there is no scientific basis.

Later generations used this sentence is actually more with the derivation of the meaning of this sentence, meaning that to do people still want to leave a little room for good. Whether you are talking or dealing with things, don't be too decisive. There are times when you don't care, say some hard words, and you may end up driving yourself into a dead end.
