The last two sentences are "safety is the law, and customers are God". We can say that we have heard these four sentences since childhood, but we still have some knowledge.

The first sentence "Time is money" is familiar to us. When we were young, our teacher told us that time is money. Later, at work, the boss will often tell us this sentence. Time is far more important than money.

And "efficiency is life", maybe you haven't heard much, but this sentence is more profound than the first sentence. Efficiency must be improved. If we are inefficient, we will waste a lot of time and energy. This is our life, so efficiency is life.

"Safety is law" is better than saying that law is safety and law guarantees safety, but this slogan is somewhat one-sided. Although the law does ensure our safety, the law is a law after all, and it is artificially formulated, and there will always be certain defects.

The phrase "customer is God" is also very familiar to everyone, and we can all see it in supermarkets in the streets. This sentence is consistent with the concept of customer first, that is to say, we must put customers at the highest point of operation and let customers enjoy the best service, so as to do our business well and make customers like themselves.
