Whether a piece of wood can be used, how to use it, what to discard, not to say by mouth, not to see, not to draw conclusions based on "old experience"-there is only one authority, that is, use a ruler to measure it, and use ink to calibrate it. One school. This is the "artisan rule". The reason why artisans are respectful is that they are meticulous in their work and always follow the principle of "the ruler has the most say". What do the "artisan rules" in this passage reveal to us? ['The rules have standards and angles. It is very clear that Ding is Ding, Mou is Mou.', 'Respecting the rules and abiding by them are the prerequisites and fundamentals for doing everything well.', 'Rules punish those who violate it, and protect and reward those who obey it.', 'Rules serve as a yardstick and criterion, providing an objective standard for people to do things.']
