Who knows how to ask an operator?

First, your understanding of superstition is wrong. In my opinion, you are the most superstitious one. What do you believe? You are superstitious about what you have learned, or what others have taught you, or your own ideas, and you avoid or deny other unknowns in this world. A great scientist once said, "A leaf falling outside the window can crush our whole science". There is another classic example. In China, we think acupuncture is a science, but at first, western society thought it was superstition and a subconscious suggestion therapy, because they couldn't detect Ren Du meridian by so-called scientific means, and they couldn't find it after thorough dissection. When they are verified in animals, they have to admit the existence of acupuncture, but it is not a strict science. Education in western society is different from that in China. Of course, I don't mean to envy foreign things. I'm just sure of their attitude towards knowledge. For example, in the west, there will be a question in the exam, "How do you think people came?" The answer can be evolution or God's creation. Yes, its purpose is not to let you get the right answer, because there is no right answer. Its purpose is to stimulate your imagination. This is the scientific attitude. In contrast, China, you only have one answer, that is, the imprisonment of thought! Cross out the word superstition in your dictionary and open a door to knowledge. Don't be intimidated by the word superstition, it will hinder your curiosity. You will find that there are many things you didn't know before, and the world is wonderful. But mind you, don't be fascinated. You will establish your own complete thought, which is not influenced by external factors. The night gave me black eyes, and I will use them to find light. For the record, I am a dialectical materialist. With your superstition, I'm not superstitious.
