In fact, the most fundamental meaning of this sentence is that the situation is urgent, and you must implement it in accordance with the laws at that time, and quickly. In fact, the phrase "as urgent as a law" began to appear in the Han Dynasty. Because of the inconvenient transportation in the Han Dynasty, some official documents were transported or conveyed very slowly at that time, so some people thought of some ways to say that the phrase "as urgent as a law" was written at the end of the official documents. As long as people who send official documents see this sentence, they will whip their horses and think it is a very important official document, so they will speed up the delivery. In fact, this is similar to what we are now. If it is a very important document, then when we have a meeting or ask others to help us burn the document, we will attach a word called urgent. This is the same as the ancients said that official documents are added as the law. In fact, this sentence has no substantive meaning. It was always used in the transmission of official documents in the Han Dynasty, but somehow it became a spell in Taoism. I think everyone should know that the phrase "urgent as a law" was said when I heard the practice of getting home. Over time, everyone forgot his original fundamental meaning.

In fact, in Taoist view, law is a kind of god beast. And this beast is quite fast, running very fast. As long as someone gives him an order, he can finish it quickly. So the law means fast. Not only Taoists use this sentence, in fact, everyone often uses this sentence in other aspects, but it is Taoism that impresses everyone. ?

In short, this sentence has a great influence on us, but it can also be seen that this sentence also has a great influence in ancient times, otherwise not so many people would use these words in their daily lives.
