When Nobody Keeps the Book: Vietnam's Combat Sports Data Gap

In a gym hidden down an alley in western Da Nang, on an afternoon so hot that the chalk dust had settled into a thin film on the mats, I asked the old coach a very simple question: tell me exactly how many fights this kid has had, how many he won, how many he lost. He looked at me for a moment, then smiled. About thirty, I think. More wins than losses. Then he opened a plastic-covered notebook gone yellow at the edges. The first page was written in ballpoint. The third was in pencil, with a few lines crossed out. From page seven onward, the paper was blank. Outside, the kid kept hitting the heavy bag, sweat running down his neck, not knowing that most of his career was living inside a blank space. The coach is not to blame. He teaches fighting, not filing. His whole life he has measured students with his eyes: watching the turn of the hip, listening to the breath, seeing whether a boy shakes the first time he steps into the ring. None of that fits into a column. But when a journalist, a scout, or a federation wants something specific, all he has to offer is memory — and memory is always generous with the people we love. That is where every problem in Vietnamese combat sports begins. Over the past two decades, martial arts here have taken on a completely different life. Boxing has professional events running on a regular schedule, with names audiences call out loud: Nguyen Van Hai, Tran Van Thao, Vo Thi Kim Anh. Muay Thai has Nguyen Tran Duy Nhat, who pulled the discipline out of the gym and onto television. Mixed martial arts promotions such as LION Championship have produced a generation of young fighters, among them Le Huynh Chau, who has become a familiar name to audiences nationwide. Traditional martial arts still hold their own ground at festivals, tournaments, and schoolyards. But try asking an ordinary question: how many times has that fighter competed, in which weight class, what did he weigh at his last weigh-in, how long has he been out, what injuries has he carried. The answer usually takes days. And often never comes. I have sat in many arenas, from makeshift halls in the provinces to carefully built cages in the big cities. Everywhere I find the same scene: people remember the fight, but nobody keeps the fight's paperwork. Results are announced over a loudspeaker, posted once on a social media page, and then they drift away. The video is not archived. The scorecards are not archived. The referees' names are not archived. A four-hour event can vanish from every record within three weeks, except for a handful of photos someone happened to take. In much of the world this is nearly impossible, simply because public databases exist that anyone can search. A professional boxer in Europe or the Americas has, by nineteen, a page listing every bout, every opponent, every venue, every result, every change of weight class. People do not love data because numbers are pretty. They keep data because it is the only thing that protects a fighter once he is no longer standing on the mat. Based on my experience covering bouts in Vietnam and abroad, the biggest gap between an emerging martial arts scene and an established one is not the number of events, the number of fighters, or the size of sponsorships. It is whether people keep the book. Sitting in the stands in Moscow, I learned to listen with my eyes and see with my ears. I trust the eye test more than any spreadsheet. But I also know one thing: the eye test, without documents beside it, is only memory. And memory cannot be opened up for cross-checking when a dispute arises. Let us go layer by layer. The first layer is the gym. In most Vietnamese martial arts schools, a student file is a notebook. That notebook holds a name, a start date, sometimes a parent's phone number. Competition results are recorded according to mood — some events get written down, some do not. Many of the best coaches I know are the ones who trust paper least, because to them a fighter says everything across three rounds, with no need for a single column of statistics. Inside the gym, they are right. But they are wrong the moment their fighter walks out of it. The second layer is the promoter. Every event builds its own system, runs it for a few seasons, stops, and the data disappears along with the event. There is no common standard for recording results and no cross-archive between events. A fighter can win one title this year and another next year, and those two achievements never meet on the same page. Fans who want to compare must gather scraps from old articles themselves, and usually give up. The third layer is the media. There is plenty of writing, but it is written to be read that day, not to be looked up ten years later. A specialised combat sports archive barely exists. During the pandemic the stands were empty, yet I never heard the hearts of fans more clearly — and I never saw more clearly how fast we are losing the ability to retell our own history. The fourth layer, and the most worrying, is health and physical condition. There is no weigh-in file, no weight-cut history, no record of time off after injury. A fighter can compete three times in a year at three different weight classes and nobody keeps a single number. In a sport where brain health and weight safety are matters of life and death, missing data stops being an administrative issue. It becomes a safety issue. The greatest loss is not that we cannot analyse. The greatest loss is that fighters cannot build value for themselves. Someone with a record but no way to prove it cannot negotiate a contract, cannot be invited to fight elsewhere, cannot attract a sponsor. A transfer is not a set of numbers. It is a farewell written into a contract — and the person holding nothing is always the one who has to sign first. Here I want to name what I consider the most counter-intuitive thing in this whole story. The first reaction most people have on hearing about a data gap is to demand more statistics. More tables, more charts, more detailed metrics for every punch. I think that is the right direction but the wrong target. Vietnam's combat sports problem is not a shortage of data because of a shortage of tools. It is a shortage of data because nobody profits from keeping it. A fighter with no file can be sold with any story at all. A gym that keeps no records cannot be checked on whether its students are rising or falling. An event that does not archive its results does not have to answer for what it claimed. And fans, deep down, prefer myth to a summary table — because myth lets us believe without having to verify. There is a soothing belief that oral tradition preserves more than paper, that the soul of martial arts lives in stories told over a pot of tea rather than in a column of figures. I have heard that line many times, and I understand why people want to believe it. But oral tradition preserves nothing. It merely transfers the right to speak to whoever speaks loudest. I realised this on a fairly ironic day. I sat down with a dossier about a fighter I wanted to profile. The dossier had a very clear title, a very formal structure, all the required sections. But when I opened it, every field was empty. No event name, no date, no result, no opponent. Someone had built a frame waiting for data, and the data never arrived. What is frightening is not the empty frame. What is frightening is the natural human reflex when facing an empty frame: filling it with something that sounds reasonable. I have seen unbeaten records built from three fights. I have seen weight classes changed to fit a story. I have seen losses relabelled as exhibition bouts, knockouts relabelled as slips. When there is no book, the fastest writer becomes the historian. When the Hoa Xuan stands dissolved into tears, I understood that a brand is not a logo but trust. Trust in martial arts works the same way, and it is more fragile than people think, because it is built from what audiences believe they saw with their own eyes. So what are the signals to watch. First, pay attention to gyms that start filming sessions and storing them by date. No software is required — a phone and a properly named folder will do. Second, pay attention to which event publishes results in a way that can be looked up years later, rather than posted once and left there. Third, pay attention to fighters who begin keeping their own files, counting their own bouts, recording their own weight classes, saving their own medical certificates. Those are the ones quietly revaluing themselves. Vietnam's combat sports data gap will not be closed by a conference or a government programme. It will be closed by people who understand that keeping the book is not a secretary's job, but the job of anyone who wants their career to outlast the memory of an old coach — however much that coach loves them. The yellowed plastic notebook in the gym in western Da Nang is still three-quarters blank paper. The question I want to leave is not for the coach, but for the kid still hitting the bag outside: if you stop training tomorrow, who will be the one to tell the world that you were ever here?
