When the Rulebook Cannot Classify the Art: Data and Verdicts in Vietnam's Combat Rings

In the last three fights I watched live at a professional combat event in Hanoi, two ended with a judges' decision the crowd refused to accept. The results were not necessarily wrong. The problem lay elsewhere: no one, not even the organizers, could clearly state the criteria used to reach those results. One fighter walked away with an arm raised. One walked away in silence. And more than a thousand people in the arena walked away feeling they had been denied the right to understand.

I work as a legal and rules commentator for combat sports in Vietnam. After every fight ends, I sit down, open the records, cross-check the provisions, and answer a question that seems simple: which criteria led to this verdict. When the answer does not exist, the problem is not with the referees. The problem lies in the system behind them.

In Vietnam, two streams of martial arts exist side by side under the single word "vo". On one side is modern combat sports — boxing, kickboxing, Muay Thai, MMA — where everything is measured by strikes landed, accuracy, and distance control. On the other side is performance and traditional martial arts — taolu, forms, demonstration routines — where value is measured by precision of movement, rhythm, and inheritance. The two sides use different languages to talk about beauty and correctness. And when events are organized together, or when rules fail to define clearly which stream a discipline belongs to, the controversy stops being about a single fight. It becomes a matter of an entire evaluation system.

This is where I want to pause. A scoring system only works when people know what it is measuring. If you measure combat sports by performance criteria, an effective striker may be undervalued. If you measure forms by combat criteria, a refined routine becomes meaningless. The error is not in the final number. The error is in a yardstick placed wrongly from the start.

When the yardstick is wrong, every number becomes evidence for a wrong conclusion.

I once followed a tournament where organizers used a single scorecard for both forms and combat categories. On the card, the categories were split evenly: technique, fitness, spirit, aesthetics. It sounded reasonable. But for a combat fighter, "aesthetics" means almost nothing. For a forms athlete, "distance control" is an empty concept. Judges were forced to score items that did not apply, and to fill the gap, they leaned on impression. Once impression replaces data, the result becomes a vote of emotion.

This leads to an observation I have held for years: in martial arts events, people argue about the winner, rarely about the method of calculation. That is the opposite of the nature of law. In any sport with referees, transparency matters more than the result. A correct result delivered through an opaque process is a fragile result. A controversial result explained through a clear process is an acceptable, even defensible, result.

In 2026, while working as an assistant editor at a football site, I had a piece rejected by my boss simply because it lacked "emotion". I had tracked passing data for a national team and concluded they were deliberately stalling. My boss said there was no solid evidence. Three weeks later, the governing body confirmed the team had been reprimanded. I kept that rejected article as a marker. The first mistake is not something to forget, but something to serve as a benchmark. From then on, every analysis of mine carried a source-data section at the end. Not to show off. So readers could check where I had been and where I had arrived.

Back to the ring. The problem is not only criteria. It is also how data is recorded during a fight. In developed combat sports, people use real-time strike-counting software, classify each attack by damage level, and log every judges' score change. This does not make referees perfect, but it makes every discrepancy traceable. When a discrepancy is traceable, people learn from it. When it disappears in silence, they repeat it forever.

In Vietnam, many events still score entirely by hand, on paper cards, with no cross-check record. When a fight ends, the cards are collected and often never published. Fans receive a result but not a reason. That information gap is not filled by law. It is filled by rumor. And rumor, as we all know, operates by its own logic, not by the logic of a provision.

I am not saying Vietnamese martial arts events do wrong. I am saying they lack something that strong martial arts cultures all have: data infrastructure. A scoring system without baseline data is like a ring without boundary lines. You can still compete, but no one knows exactly where the line is.

Interestingly, this gap is not unique to martial arts. It is a general pattern across any evaluation system based on perception. In football, it takes thousands of frames per second to determine an offside goal. In martial arts, three judges still look with the naked eye and vote by intuition. Two sports, two levels of reliability. But both obey the same rule: Data stays silent until someone asks the right question.

So what is the right question here. Not "who won". But "what did we measure with". That is the question organizers, referees, and audiences should internalize before arguing. When that question is not asked, every debate is meaningless. People argue about a fight, but are really arguing about two different yardsticks that nobody names.

There is a paradox I have observed for years. The more devoted the fans, the harder it is to accept a result against their wishes. That is natural instinct. But for this reason, the responsibility for transparency belongs to organizers, not fans. Fans are not equipped with rules to read a fight. They are equipped with emotion to experience a fight. If organizers do not supply the rules, emotion will write the rules for them.

I once watched a fighter lose a bout I believed he won. I rewatched the footage six times. By standard combat criteria, he had more effective strikes. But he lost, because the criteria used were mixed, with a category for "fight control" scored by judges' perception. I am not saying the result was wrong. I am saying it could not be verified. And a result that cannot be verified is a result that cannot be defended.

This is something Vietnam's martial arts community could learn quickly, if it wanted to. No expensive technology is needed. Just three changes: publish the scoring criteria before a fight, record scores round by round, and explain publicly after a fight when the points are close. These three steps do not remove the excitement of martial arts. On the contrary, they turn each fight into a trustworthy product, and a trustworthy product is always worth more than a controversial one.

I know someone will say martial arts is art, not science. But that is not right. Martial arts is both art and science. The art belongs to the fighter. The science belongs to the rules. Mixing the two and calling it "tradition" is a clever way to dodge the responsibility of organizers. Genuine tradition does not remove transparency. Many ancient Asian schools recorded detailed test forms, passing standards, and lineage history centuries ago. They were more transparent than we imagine.

So when we hear a losing fighter cry foul, let us stay calm. When we see fans split into camps, let us slow down. Because in most cases, the dispute is not about the winner. The dispute is about the gap between a rule and how it was applied. Filling that gap harms no one. It only makes everything clearer.

Once I attended a training session at a small gym on the outskirts. No audience, no media, no cameras. Just fighters, a coach, and a scoreboard on the wall. The coach scored each round in chalk, called out each criterion aloud, and asked fighters to repeat why they won or lost. That session reminded me of something: when the field is empty, the rules remain, and people obey not out of fear, but out of understanding. An empty field still keeps its rules; people just see more clearly when there is no noise.

Scaled up to a professional event, the principle does not change. A judging system that wants to be trusted must do exactly what that coach did: call the criteria aloud, record the scores, and explain the result. There is no other way. Any effort to replace transparency with the individual talent of one good judge is only a temporary fix. Individual talent cannot be transferred. A system can. And a good system trains many good judges instead of depending on a few.

This is why I believe the future of Vietnamese martial arts lies not in inviting more foreign experts, but in building domestic data infrastructure: standardized scorecards, traceable fight records, and a transparent complaint process. Those three things do not require a large budget. They require discipline. And discipline, as I have learned from years working between two cultures, is learnable, provided people truly want it.

I do not write every commentary this way out of habit. I write this way out of a belief: serious readers do not need strong declarations. They need to see the path of an argument. They need to know what question I asked, what data I gathered, what hypothesis I discarded, and why. When I show them the path, they can verify it themselves. And when a reader can verify, the writer is no longer someone imposing a verdict. The writer becomes a fellow examiner.

As for fans, I want to say this. If next time you watch a fight that ends by judges' decision, ask yourself: are you arguing with the result, or with a criterion that was never published. If it is the latter, you are not alone. Many people, including me, have entered debates forgetting that we were never given the rules of the game. That is what needs to change, and the change must start with organizers, not the stands.

I have a personal rule when analyzing any verdict: if I cannot write on a single page the criteria used to reach the result, I do not conclude. Not because I lack an opinion. Because I do not want to become a biased referee — the worst thing for someone who reads rules for a living. Referees do not create errors; they only record what the rules already contain. If the rules are unclear, the error is not the referee's. The error belongs to the rulemaker.

The ring is where emotion peaks. That is the nature of martial arts, and no one wants to change it. But emotion and verdict are two different layers. Emotion belongs to the stands. Verdict belongs to the system. When the two mix, controversy never ends, because no one can argue fairly with another's emotion. But people can argue with a provision. A provision can be cited, compared, amended. Emotion cannot.

So my question for Vietnam's martial arts organizers is not "who won". It is: are you ready to publish the criteria before the fight begins, record the scores during the fight, and explain the result after the fight. If the answer is yes, controversy will decrease without a single new rule. If the answer is no, then no matter how correct the result, there will always be doubters — and they have the right to doubt, because you did not give them the tools to understand.

A mature martial arts culture is not measured by the number of fighters or fans. It is measured by the number of times fans trust a result without needing to ask again. When that trust appears, everything else follows.
