If it were you, would you dare to challenge yourself in "freehand rock climbing"?

I certainly can't be afraid of heights, but this spirit is worth learning. China director Jimmy Chin and his shooting team are professional rock climbers, and they have a deeper and more thorough understanding of rock climbing than ordinary people. So they often shoot easily and are accurate every minute. The film revolves around climber Alex. In order to climb the steep Cedar Rock in Yosemite National Park by hand, he conducted two years of exploration and training, and made a positive interpretation of extreme rock climbing from the side. In the last half hour, the film recorded Alex's four-hour unarmed climb over 900 meters of Emirates Rock from all angles. After reading it, I had a cold sweat and my mood was hard to calm down for a while. My ears always echo that sentence: perfect or dead!

I have seen many movies about extreme sports. Like Walking in the Clouds (tightrope walking in New York World Trade Center) and Breaking the Height (climbing Mount Everest), these feature films adapted from real events are thrilling, but there are too many special effects to be worth pondering. However, the documentary "Freehand Rock Climbing" has no special effects, only records, but let the audience see the realism of challenging nature and the magnificence of harmonious coexistence between man and nature.

On the other hand, in the eastern society, our education advocates following the rules, step by step, and imprisons the thinking of challenging the limits in the thunder pool. What is outstanding is that it solidified the exam-oriented module, strengthened the exam-oriented questions and put an end to the voice of doubt. Without negation, there is no challenge. Without challenges, we can never innovate. Who knows that questioning is the driving force of innovation?

From the basic education model to the national and scientific level, it is not difficult to understand why the western scientific and technological innovation ability is so strong. The problem is that they have this thinking of challenging the limits from top to bottom. From many Nobel Prize-winning western scientists (Japan is a western country), we can see the role of challenging extreme thinking in promoting science and technology.

Now the whole country is vigorously promoting scientific and technological innovation, and is striving to turn "Made in China" into "Created in China". In my opinion, the dream of strengthening the country through science and technology must begin with education. There are thousands of layers on the wall. Just like freehand rock climbing, the only way out is to keep going up.
