On January 3, 2026, I filmed my 2000th video. Actually, I have filmed over 2300 videos along the way, and this is the 2000th one about application cases of die steel. I have also filmed over 100 video diaries and over 100 mini-encyclopedias about die steel, but both of those were intermittent.
Among the cases related to die steel, I have filmed the most, with 2000 videos to date. I would like to summarize and review this video.
My first video started on January 5th, 2019. At that time, when I suddenly browsed Tiktok for some content related to our die steel industry, I found that whether it was about die steel, mold design, mold manufacturing, or mold training, most of the videos were humorous and did not cover any content. At that moment, I felt that if I were to talk about die steel content, it might be an opportunity for me.
Since January 5, 2019, I have been uploading videos on Tiktok and various other platforms. As of today, January 3, 2026, I have already made 2,000 videos. Over the past seven years, that’s equivalent to 300 videos a year. These seven years have brought about significant changes to me.
First and foremost, I used to be involved in offline business. Through seven years of hard work, I have completely transitioned to online business, which is a world-shaking change for me.
Secondly, speaking from my personal experience, I used to run a small factory offline and was too shy to speak in front of a crowd. But now, when I make videos, I don’t need to write a script in advance. Just like this video today, I improvised. I’ve also done over 260 live broadcasts. None of these require advance preparation or planning. I can start at any time. This has greatly honed my skills as a person.
From our company’s perspective, over the past seven years, we have relocated and expanded our production scale. Currently, three Fortune 500 companies procure Yuhui tool steel, and Kyocera has been doing so for seven consecutive years. This has brought about tremendous changes to our company’s development.
Meanwhile, my personal status in the industry has undergone a tremendous transformation. I have gone from being an unknown figure in the industry to being a topic of conversation during meals and talks. I am also very happy about it.
Before June 5th, 2019, no one knew what kind of die steel 8566 was. As of today, both online and offline, people all over the country are copying my 8566 die steel. As netizens say, 8566 is even more famous than you, Wu Dejian. Those who know 8566 all know you, Wu Dejian. Many peers have said that 8566 is the legend of Mr. Wu.
Over the past seven years, it has been a world of difference for me. The phrase “two worlds, old and new” aptly describes not only the effectiveness of 8566 die steel, but also my personal experiences over these seven years.
Our company’s 8566 anti-chipping steel, high-toughness LG die steel, non-stick 8503 die steel, and high-temperature-resistant 8433 die steel have now become the targets of imitation and counterfeiting by our industry peers across the internet. This is also a form of recognition from my peers. From never being able to shoot videos to being able to do so at any time now, and from never daring to speak in front of the public to having done more than 260 live broadcasts, I believe this constant repetition and unceasing practice have also changed me.
Making videos has brought about a tremendous change for me, whether it’s in my personal life, my personal abilities, the development of our company, or the transformation and focus of our products. I am deeply grateful to the current internet platforms, and I also thank the Tiktok platform for giving me this opportunity.
Of course, you could also say that over the past seven years, you have been persisting and working all the way. Because you have been doing it for a long time, you have gained such benefits. You could also say that, but if a person is not shaped by the times, no matter how capable they are, it’s useless. I am very grateful for the present moment, for the Internet, and even more for all the major platforms that give ordinary people like us a chance to speak out. I also thank you, the person reading this, and all the fans who follow and trust me. The support you give me is endless. Without your recognition, I couldn’t have done this for seven years.
Over the past seven years, I have read numerous books on die steel and accumulated extensive experience in metal materials. Although sharing this knowledge with others has been helpful in their selection of mold steel, it has actually been the greatest personal improvement for me. Now, with just a general understanding of the mold’s condition, I can determine the appropriate die steel to use.
We, Yuhui die Steel, are not only a pre-hardening factory specializing in die steel, providing both die steel and heat treatment. We also boast a vast array of case studies. Over the past seven years, I have successfully resolved complex issues related to mould material selection, manufacturing, and usage for more than 4,000 enterprises. The case studies I have accumulated are unparalleled in the industry, even among those who specialize in this field. I have filmed 2,000 case videos on die steel in one go, making me the only one among 1.4 billion Chinese people, and even the only one among the global population of 8 billion.
In this summary and recollection of Video No. 2000, I want to say “thank you” to you, for your attention and trust. In the days to come, I will continue to focus on die steel with anti-chipping, high toughness, and non-stick properties, making steel grades that the global top three do not produce. I will use my own products and case experiences to help users achieve high efficiency, long lifespan, and low cost usage, doing things with a hundred times more dedication than the users themselves.
At this moment, I am filled with emotion. Of course, I also hope that you will continue to follow me and give me your support, as we move forward hand in hand.
