The Classification Error in Vietnamese Combat Sports: Three Scoring Systems, One Arena

At a press conference following a martial arts club championship at Phu Tho Sports Arena, a young reporter raised his hand and asked me: "Why is it that this vovinam fighter won, but I can't find any record of him online, while an MMA fighter who lost has a full profile?" I answered with another question: "Which ruleset were those two fighting under?" He went quiet. In that silence, I realized what seventeen years holding a microphone had taught me: an entire combat sports scene is misreading itself, and it starts with a step almost nobody bothers to take — the step of classification. In Vietnam, under the single roof called "martial arts," at least three different measurement systems coexist. The first is the performance system: forms, kata, taolu, where the athlete has no direct opponent but a panel of judges. The second is the rules-specific combat scoring system: sanda, vovinam combat, traditional martial arts combat — where scoring depends entirely on each event's specific rulebook. The third is the professional combat sports system: MMA, boxing, kickboxing, Muay Thai, where records are measured by wins and losses, finish rates, and significant strikes. These three systems do not share a ruler. Yet on newspaper pages, in news feeds, and even on the electronic scoreboards of more than a few grassroots events, they get poured into one column. That is a classification error. And it is not a small one. I came to sport by a winding road. In 2026, I started writing from abroad, then moved to Vietnam, and the fateful day was March 2026, at Lạch Tray Stadium, in the match between Hai Phong FC and Ho Chi Minh City FC. When I asked the visiting head coach about his tactical formation, he frowned: "What does a girl know about formations?" I did not argue. I simply counted. Seven successful dribbles by the left winger, number 17; three chances created; one assist. My analysis piece afterward was the most-shared of the week, and by year's end I was sent to cover the 2026 World Cup. My first lesson was not "data matters." My first lesson was: data only matters when you know which measurement system it belongs to. The second lesson was more expensive. On 30 June 2026, in a World Cup round-of-16 match in Russia, I mispronounced Kylian Mbappé's name and was mocked across the internet. After the match, France beat Argentina 4-3 thanks to Mbappé's brace and a penalty. I rewatched all 25 of his Ligue 1 matches from the 2026-18 season to understand where I went wrong — not in pronunciation, but in having slapped a label on a person too quickly. "Misname one person, and you remember the lesson for life." Since then, the first thing I do when analyzing any athlete is establish where they compete, under what rules, and by what standard they are measured. That is precisely the step Vietnamese combat sports is skipping. Start with the first system — performance. A forms athlete or taolu athlete has no "head-to-head record." No "win rate." No "finish rate." They have judges' scores, the difficulty of the routine, the precision of movement, and deductions for technical errors. If you apply MMA's win-loss logic to a forms athlete, you conclude that the person "has no record at all." But that is not a lack of achievement. It is a completely different measurement system that you are refusing to read. Vovinam, founded in 2026 in Hanoi by the late master Nguyễn Lộc, has featured in the competition program of multiple SEA Games, with both forms and combat disciplines running side by side. A vovinam athlete can be a national forms champion without a single combat bout on record. Search for "achievements" and you will find nothing. Ask the right question and you will find an entire career. The second system — combat scored by its own rules — is the most dangerous place, because it is a hybrid of two worlds. Sanda, the combat discipline of wushu, scores by landed strikes, throws, and ring-outs. A sanda fighter can win by pushing an opponent off the mat twice — something that means nothing in MMA, where the octagon has no concept of "out." Vovinam combat has its own rulebook on leg techniques, locks, and scoring by body region. Traditional martial arts combat has rules that differ even further, depending on the event. When grassroots promotions stage multiple disciplines in one night, organizers often merge everything into a single "fighter record" table for media convenience. I have seen such tables. A sanda fighter with five wins by pushout sits on the same line as an MMA fighter with five wins by submission. The number five is identical. The meaning is entirely different. The third system — professional — is the only one with a relatively complete measurement infrastructure. MMA has fight databases, unifying rules bodies, and international fighter profiles. Boxing has four major sanctioning organizations and their ranking systems. Kickboxing has Glory and K-1 with their own rulesets. Muay Thai has Lumpinee and Rajadamnern with a traditional scoring system very different from the West's. Even within the professional tier, the boundaries between systems are complicated enough. But at least there, people know what they are measuring. Vietnam's problem lies in the way journalists, investors, and even some organizers build bridges from the third system back to the first two, carrying the wrong numbers and the wrong expectations across. I call it the "MMA-ification of everything" effect. A visually brilliant vovinam talent is expected to switch to MMA to "have a future." A sanda world medalist is undervalued for lacking a "fighter record." A traditional martial arts event is asked by a sponsor: "Where are your rankings?" — when the discipline was never built to have rankings. What is the result? Resources flow to what is easiest to measure, not to what needs them most. Brands sponsor whatever can be photographed next to a scoreboard. Media cover whatever yields a short headline. And disciplines that cannot "package" themselves as a record table — performance vovinam, traditional martial arts, the ritual-heavy and culturally dense lineages — quietly fade. In one conversation with a colleague in Hai Phong about the summer of empty stadiums in 2026, I brought this up again. Back then, when competitions returned to spectator-free venues, I practiced broadcasting using only sound — the roll of the ball, the breath of players, the shouts of coaches. "Symphony of Silence" became a hit. Many said they could "hear" the match through the words. I learned that when you have no image, you are forced to listen on the right channel. Vietnamese combat sports is the same: when you lack a good scoreboard, you are forced to listen on the right measurement channel. And sometimes "hearing through the eardrum" is more honest than looking at a number column stitched together in the wrong place. I want to pause here, because this is where I am often misunderstood. Many read my work and think I advocate "metricizing" all Vietnamese martial arts to international standards. I do not. What I oppose is not measurement. What I oppose is measuring with someone else's ruler, on a subject that does not belong to that ruler. Here is the counterintuitive angle: the wave of importing MMA metrics into Vietnamese combat sports sounds scientific, but is in fact a category error dressed up neatly. "Data does not betray you; you just put your trust in the wrong place." A number from the wrong measurement system is more dangerous than a subjective compliment, because it creates the illusion of precision. When you say a vovinam fighter has a "0% win rate," you are no more honest than a fan shouting from the stands. You are simply lying with more formal syntax. That is why the classification step — establishing which system the subject belongs to before analyzing — is not an administrative formality. It is the foundation. Skip it, and every data building you erect leans. There is another view worth discussing: does strict classification fragment Vietnamese combat sports, making development harder? I believe the opposite. It is precisely because everything is merged that no discipline has its own voice in sponsorship negotiations. When each system has its own measurement standard and an organization to certify that standard, sponsors can invest in specific lines — a national vovinam event, a school sanda league, a regional traditional martial arts ranking. Classification is not divide and rule. Classification is the condition for independent survival. So what should be done? First, sports media need one simple rule: before writing anything about a fighter, answer the question "which ruleset does this person compete under." If you cannot answer it, do not write. Second, organizers of multi-discipline events should display a separate measurement system for each bout, rather than merging everything into one record table. A small line reading "Sanda — scored by pushout rules" under a fighter's name can save an entire analysis from distortion. Third, discipline federations should build and publish their own measurement criteria, rather than waiting for someone else to assign them an imported standard. I know this does not sound exciting. It has no knockout moment, no roar from the stands. It is just a column in a data file. But "the numbers tell the story; the storyteller only needs to sit down and listen" — and the worst storyteller is the one who listens on the wrong channel and then retells it in a confident voice. Years ago, I thought I would pursue a professional athletic career. My body would not let me continue. But it was precisely those training hours behind closed doors, with not a single spectator, that taught me the most important thing about truth in sport: "When the stadium is empty, the loudest applause is your own." Meaning, when no one steps up to recognize the measurement system you follow, the person inside must be the first to recognize themselves by asking the right question about themselves. Vietnamese martial arts is in such an empty stadium right now. No one outside is knocking on the door demanding to classify us properly. We must do it ourselves. Some will say this is a small matter, an academic matter, something that does not help a fighter worrying about next month's training fees. I disagree. A fighter classified into the wrong system, judged by a ruler not meant for them, will be paid wrongly, invited to the wrong events, and told the wrong story by the media. From a single classification error at the first layer, the entire value chain behind it tilts. Conversely, when we take three seconds to ask "which system is this," everything behind it — money, events, stories — has a chance to stand upright. Tomorrow, there will be another event. Fighters will again step onto the mat under three different rulebooks in a single evening. Young reporters will again raise their hands and ask me the same old question. What I want to do is not hand them an answer, but teach them the first question that must be asked. Because in a sport where three measurement systems share one arena, the person who knows what they are measuring is the one who can tell the story correctly. Everyone else, however full their hands are of numbers, is still hearing through the eardrum and mistaking it for clear sight.
