Vietnamese Wushu and the Data Gap: When Taolu Is Read With Sanda's Ruler

On the electronic scoreboard of the wushu arena at the SEA Games 31 in Hanoi, in May 2026, the score of a women's jianshu routine appeared with three digits after the decimal point. I sat in the press area, opened the online results file, downloaded it, and received exactly one line: athlete name, nation, total score. No difficulty score. No deduction list. No breakdown by movement. In the ring next door, a sanda bout ended in a knockout, and the colleagues around me had plenty to write with: the timing of the count, the number of strikes landed, the stance after taking a blow. They wrote about power, about nerve, about the moment. Then the jianshu routine was written with exactly those same words, even though it had never been judged by those criteria.

It took me several years to name the phenomenon correctly: reading with the wrong ruler. A taolu routine and a sanda bout sit under the same wushu roof, wear the same national-team colours, and are counted into the same medal table of the Vietnamese delegation. But they run on two logics so different that using one vocabulary to describe both is an act of epistemic vandalism. Spectators come to believe that taolu is scored like a fight, and from that belief, every conclusion downstream is skewed. No correction catches up with a prejudice that has hardened into habit.

In taolu, the International Wushu Federation scores on three groups: technical difficulty of the movements, performance quality, and errors requiring deductions. Loss of balance, wrong angles, insufficient height, missing pause — each carries its own deduction value. There is no concept of knockout. There is no direct opponent on the floor. There are no landed strikes. Sanda is the reverse: two people, one platform, judges scoring effective strikes, throws permitted, counts permitted, and victory by knockout. Technically, sanda is closer to kickboxing than to the jianshu routine unfolding twenty metres away.

The SEA Games medal table does not separate the two branches. It records "wushu", plus a medal. Most news copy follows suit. When a data system merges two different sports into one line, every comparison drawn from that line loses its value. I tried something simple: counting how many Vietnamese articles over the last three SEA Games used the words "knockout" or "finish" when discussing taolu. The sample was not large enough to call a finding, but large enough to reveal a habit.

Vietnam's wushu tradition is not thin. In the taolu branch, Duong Thuy Vi is the name attached to multiple SEA Games gold medals in women's jianshu and qiangshu; Hoang Thi Phuong Giang also left her mark on the regional stage. The sanda branch has produced athletes who have represented Vietnam at SEA Games and Asian championships. But if you ask me how many difficulty points were inside the gold-medal routine of any of them, I have to say I do not have that figure, and there is no public source where I could look it up.

That is the moment I am forced to write the thing this profession rarely agrees to write: not yet determinable.

What is worth noting is that the data gap in Vietnamese martial arts lies mostly not in collection. It lies in publication.

In the combat disciplines, the gap sits in body weight. A boxer or Muay Thai fighter steps on the scale, the figure appears, and it vanishes from every news item within twenty-four hours. Nobody records what that person weighed three weeks earlier, whether they had previously missed weight or come in over, or why they once had to drop a division. Based on my own experience covering bouts across several SEA Games and Asian championships, I have never seen a published weight log for a Vietnamese fighter. In sports medicine, rapid weight reduction is one of the variables with the highest predictive power for health incidents. But that variable only exists if someone is willing to record it.

Further back, past the end of the career, the gap is wider still. Nguyen Tran Duy Nhat, a multiple-time Muay Thai world champion, is famous enough that people remember the name. He is the exception. Most Vietnamese fighters end their careers with nobody tracking where they go, what they do, what they live on. Esports players face the same void with a particular cruelty: their competitive lifespan is shorter than a footballer's, and the post-retirement support system is close to non-existent.

I learned the value of data from something very small. In 2026, while working mid-level for a digital sports platform in Binh Duong, I was assigned to film the national youth athletics championships. A sixteen-year-old from Dong Thap named Nguyen Thi Thanh Van finished twelfth in the 200 metres. There was nothing there to write about. But when I put the slow-motion footage into the computer, her step frequency in the opening fractions of a second after the gun was the fastest in the entire competition. I wrote a piece proposing a change to her drive-phase technique, and a veteran coach laughed in my face: "A woman, pretending to understand biomechanics." I did not back down. I gathered data from three more slow-motion sessions. Six months later, Thanh Van broke the national youth record at 23.48 seconds.

What made that article possible was not my intuition. It was the existence of a camera. Remove the camera, and the story disappears, and a sixteen-year-old athlete goes on finishing twelfth, invisibly.

GPS numbers do not lie; only the people reading them do. But before anyone can read them correctly, there has to be data to read. And across most martial arts in Vietnam, that data does not publicly exist.

In 2026, when the pandemic wiped out the fixture list, I built a series simulating cancelled matches with a football video game, alongside an interactive column inviting readers to vote on substitution options. The first edition drew two hundred thousand interactions, triple the channel's previous record. Veteran journalists winced. I understood why they winced, and I did it anyway, because I followed one rule: simulated data must be labelled as simulation. Nobody was deceived. An empty stadium taught me that passion does not need a seat, but it also taught me that when there is no real match, the only honest way to write about a match is to state plainly that it is a hypothetical.

Not long ago, I processed an analytical document that arrived with full headings, a full framework, full tables. But the input data section was empty. No athlete names, no event, no result, no dates. Only a generic classification label remained. There were two ways to handle it. The first was to keep writing, to fill the gaps with background knowledge, and to produce a text that reads very smoothly and is right about nothing. The second was to declare a null result, state exactly what was missing, and propose a repair path. I chose the second, and I consider it the most valuable conclusion that document produced.

A null result is still a result. The only honest conclusion when the data is empty is: not yet determinable.

That sounds like a lazy person's joke. It is the opposite. Writing "not yet determinable" costs more than writing a wrong conclusion, because it requires the writer to prove that they walked the entire road searching for data and that the road dead-ended. A wrong conclusion takes three minutes. A declared null takes a week of searching, and enough self-respect to accept that the week produced nothing to publish.

I have paid the price for skipping that principle. At the 2026 World Cup in Russia, during the opening match at Luzhniki, I called the midfielder Aleksandr Samedov "Semidov" three times in the first half. Social media reacted furiously; someone advised me to go and write about fashion instead. I did not delete the post. I published a public apology, then spent thirty days rewatching forty broadcast matches to record how each player's name is pronounced in the local language, built a glossary with cultural notes, and trialled it in the quarter-finals. When I mispronounced a player's name, I learned how to listen to the match.

Since then I have applied a hard rule: every name must be verified against three independent sources before publication. A name that cannot be verified means a fact that does not exist, and a fact that does not exist must not be written.

At this point the story leaves the arena and walks into the meeting room. Vietnamese sports journalism does not lack data in the sense of lacking sources. It lacks the habit of saying "I don't know". In a press room, the sentence "I don't have the figures to answer that" is treated as a sign of weakness, while the sentence "I feel that" is treated as a sign of expertise. The two standards are inverted, and we have lived with that inversion long enough to forget it was ever a choice.

A blank scoresheet benefits the organisers. A blank weigh-in record benefits anyone who does not want the weight-cut process seen. A blank list of retired fighters benefits everyone who does not want to be asked what those fighters are living on. A gap is not the natural state of information. It is a decision, and someone always benefits from that decision.

I say this as an outsider who is nevertheless inside. Born in China, living and working in Vietnam for nearly two decades, I see things that insiders have grown numb to. A results sheet that shows only a total score teaches audiences never to ask why one competitor beat another by half a point. When that question is never asked, the scoring standard drifts, and it drifts until nobody remembers what correct looks like.

The repair is cheaper than people assume. A breakdown sheet for every taolu routine, published immediately after the event, listing difficulty score, performance score and each deduction. A public weight log for the combat disciplines, recording both pre-event and competition weight. A post-retirement registry for fighters and esports players. None of those three requires a large budget. They require one person to sign off.

Data points to talent, but the heart points to the champion. And the heart cannot score difficulty points. What can score difficulty points is a system with a person behind it, accountable for every published figure. If the federation published the breakdown sheet for every routine, how many young coaches would learn to judge for themselves instead of learning to copy down the total? I have no data to answer that. I only know we are without an answer because nobody has yet been willing to publish the data that would provide one.
