What wonderful things have you encountered during your stay, business trip or travel?

There is a saying, the world is big, and there is no wonder. I believe many people have traveled or traveled. When you meet more things and more people, you will find that some people do wonderful things. So what are the wonderful things that people feel when they are on a business trip or journey?

A box carrying a suitcase.

For the convenience of business trips, many people use suitcases, but on the way, suitcases are usually towed away. Did you see the man with the suitcase? Once, I was on a business trip and met such a person. He is carrying a big suitcase inside, which looks hard. So someone came forward and asked him why he didn't pull the suitcase. His answer is that this can reduce the friction of the suitcase wheels and prevent them from being easily damaged. The original intention of the bold wheel is to facilitate people. Isn't this way of thinking like a donkey who doesn't ride a horse and walks with a donkey on his back? Isn't such a thing wonderful?

Second, the thermal plug should be divided into positive and negative poles.

I believe that many people use hot water to boil water, and they all know that the plug of this electrical appliance is positive and negative, which is also the common sense of junior high school physics. But on a business trip, I met such a thing. A person uses a label to attach a rapidly heating needle to the anode and cathode. Asked about the reason, his answer was that if the difference between the positive and negative poles was reversed, the temperature would not rise quickly. This is his summary of experience after a long time. Seeing this, I looked at him seriously and didn't know how to explain it to her. Maybe he really thinks so. For such a person, we can only persuade him to seriously review junior high school physics. Now I'm making such a joke.
