Don't be dogmatic about reading!
The rules and dogmas we have summarized in engineering are all summed up in certain production practices, and all have a scope of application. Some rules have a wider scope of application, and some rules have a narrower scope of application.
A rule with a relatively narrow scope of application is reliable within its scope of application, and may be unreliable and inappropriate if it deviates from this scope of application. We sometimes encounter some contradictory rules in practice, which is probably caused by the different scope of application of these rules.
When learning the rules, you must pay attention to the scope of application, otherwise the dogmatism is saying this kind of error.
There are also some rules that may be called conventions. These conventions require a certain learning cost, and some additional costs may be paid for
implementation. If the benefits of implementation cannot compensate for these costs, then these conventions are also inappropriate.
Generally speaking, the finer the rules, the narrower the scope of application may be, unless the scope of application is allowed to be considered when these rules are formulated.
Therefore, special attention should be paid to the implementation of this rule.
