With the rapid development of science and technology in modern society, people often feel anxious and uneasy about things they have never experienced. In this case, everyone wants someone to guide them, and this kind of popular science video solves this problem well.
We need people who have experienced this kind of experience to express boldly.
It is developing rapidly now, but not everyone can adapt to this speed.

So we need people who have had this experience to help.
