Vietnamese martial arts is standing on an empty data table — and that's the scariest thing

Don't read the numbers. Read the story that numbers don't dare to tell. At three in the morning at a gym in Hai Phong, I received an email from a young analyst. He sent a data sheet about a boxer who is currently viral on social media, with a note: "Kim, please take a look. The data is empty, I don't know what to write." I opened the file and saw blank cells. The match had taken place the night before, but no one had counted the exact punches, no punch speed, no movement distance, no pressure per round. Only a boring score: 3-0 for the home boxer. That is a familiar scene for me — someone who has spent 25 years observing sports from press rooms to rings, from Korea to Vietnam. I've witnessed countless top matches, from the 2026 World Cup to SEA Games, but what always bothers me is this: when the numbers are empty, people still write. They write with emotion, with reputation, with rumors. And that's when Vietnamese martial arts is quietly heading into a crisis. In 2026, stadiums were empty, but I have never heard them so loud. During the pandemic, I came up with the idea of a series "Football in My Head," recreating classic matches from memory and historical data. At that time, I realized that data never lies, but lack of data is more dangerous than a lie. It makes us believe we are seeing the truth, while in fact we are looking at a broken mirror. Back to boxing. That 3-0 match, I know the losing boxer is Le Van Hung, 27 years old, from a small gym in Binh Dinh. He is undervalued because his record is just 12 wins, 4 losses. But I watched him train last year, and I noticed something the numbers don't reflect: his ability to read opponents is excellent. In the third round last night, he knocked down his opponent with a left hook, but the referee didn't count it because he thought Hung pushed. No slow-motion replay, no data on impact force, and so a deserved victory became an unjust loss. From the bottom of the rankings, I see an empire waiting to wake up. The family martial arts schools in Binh Dinh, Nghe An, and small gyms in Saigon are nurturing fighters with great skills, but they are left behind because no one bothers to measure them. Meanwhile, the media only circles around a group of star fighters who have advertising contracts and foreign coaches. This is not something I made up. Look at the Vietnam Boxing Federation rankings: the top ten are always old names, while youth tournaments only draw a few hundred spectators. I don't believe in contracts. I believe in legs and a cool head. But when there is no data system to evaluate that cool head, how can we know who deserves the belt? In recent years, a few tournaments have started testing sensors on gloves, but the cost is high and the data is not made public. Vietnamese journalists often rely on personal feeling, and each article becomes a bet on their own reputation. Remember the 2026 World Cup. Spain, with 70% possession, lost to Russia on penalties, and experts criticized Russia for defensive football. I wrote an article praising their concrete block as an artwork and was heavily criticized. Then France won with practical football, and the story changed. What I mean is: if we only look at possession, we miss smart defensive structures. In Vietnamese boxing, if we only look at win-loss records, we miss a whole generation of talented street fighters. Strategy is only a coat. The person wearing it is what I examine closely. But to examine a person, I need more than a subjective view. I need reaction speed, reach, effective strikes in different situations. Numbers know what you don't know — that's what I often tell my colleagues. Read carefully, if numbers are not enough, create them yourself. I remember once in Australia, when I was a young reporter, an old boxing coach taught me to count punches by hand — no machines, just a pen and paper. He sat at ringside, each time his fighter threw a punch, he made a mark. After the fight, he had a precise stat that even referees were surprised by. That was my start with data, and it changed my life. Yesterday, I sat with that young analyst and told him, "If there are no numbers, create them." And we started a small project: collecting data from matches at a local tournament in Hai Phong. We used phones to record every round and then analyzed frame by frame. It was tiring and slow, but after three weeks, we had a first data set on ten unknown fighters. The result was surprising: a young fighter named Pham Van Duc had a striking accuracy of 42%, higher than the current champion. No one believed him, because he had only one win in his last three fights. But the data showed he had faced stronger opponents, and referees had stolen at least two fair wins. That's when I realized Vietnamese martial arts does not lack talent. It lacks a system to protect the truth. In football, teams have dozens of analysts, GPS devices, and their own data rooms. In boxing, MMA, or traditional martial arts, even a national championship only has a simple Excel sheet. We are at a time when the world is moving to artificial intelligence, and Vietnam is still counting punches with wooden sticks. The incident in Binh Dinh, where the referee did not recognize a knockdown, is a symbol of that backwardness. In modern combat sports like MMA, the UFC uses effective striking statistics to decide scores. In Vietnam, fighters still depend on the referee's eyes, and people accept it as part of the game. But no, that is not fate. That is managerial laziness. I could be wrong, and I always welcome that. Some friends in martial arts tell me, "Kim, you're too heavy on data. Martial arts is art, not mathematics." I respect that opinion, but I will not back down. My argument is based on 25 years of watching combat sports — from anecdotal bouts in Seoul to youth tournaments in Hanoi — and I have never seen a great fighter born from ambiguity. They all know exactly where they are strong and weak. Muhammad Ali kept training diaries, Bruce Lee wrote notes on every move, and Korean fighters like Hong Man-kin were measured millimeter by millimeter. In the near future, I believe data systems will become an inevitable part of Vietnamese martial arts. The question is not whether, but who will pioneer. From now on, I pledge: before writing about any fighter, I will find a way to collect data if it is not available. If all sports journalists do the same, Vietnamese martial arts will no longer have to crawl on empty numbers. The world is watching combat sports transform through technology. Thailand has used camera tracking in Muay Thai since 2026, Japan applies AI to analyze Judo techniques, and Korea — my home country — has built a sports data center with government participation. Vietnam, a country with ancient martial arts schools and millions of young people boxing in search of glory, is being left behind in the data game. But I see a huge sleeping resource: passionate fans, dedicated coaches, and young tech developers. With the patience of a regular season, I believe that by 2030, Vietnam will have a unified martial arts federation with open data. Mark my words: that will be when the martial arts empire of Vietnam awakens. But if that year still sees empty data tables, I will stake my reputation and say: we have lost a golden generation. Don't just read the numbers — start recording them. That is the story numbers don't dare to tell, but it is the story Vietnamese martial arts needs most right now.
