Vietnamese Volleyball and the Battle Against Oblivion

The sports arena of Hung Yen province was filled with familiar cheers, but on the press bench, I was noting something that had never appeared in my notebook. "Missing data," I wrote as my camera captured the image of a substitute setter in the volleyball national championship semifinal. That girl's face was flushed, not from fatigue but from confusion. After entering the court, she made three sets, none of which created an effective attack. The coach nodded for her to rest at the end of the set. She was not named in any interviews, and her sets—the lifeblood of a team—were recorded in no statistical table. That night, when I asked the league's deputy communications director about the setters' accuracy rates, he looked at me as if I were speaking an alien language. "We only have data on points and successful attack rates," he replied. "As for the moment the ball touches the setter's hands, no one tracks that." He pointed to a thick stack of handwritten numbers, logged by an intern. In an era when sports data is ascendant with hundreds of metrics like PPDA, reception efficiency, and attack tempo, Vietnamese top-level volleyball is still swimming in the twentieth century. My mind drifted back to my days behind the camera in Japan, at a club-level tournament. There, even an amateur team had at least two dedicated recorders, and every rally was tagged with data on time, location, and participants. When a play failed, the system would identify who did what. In Japan, "they may not tell the truth, but they absolutely never lie"—a philosophy I learned from a Chinese basketball news site. But in Vietnam, the "truth" on a volleyball court exists only in the memories of a few. Slumped in the stands, I began to list what I wanted to know about the match I had just watched. What was the winning team's perfect reception rate? How many service errors in the second set broke their scoring rhythm? Which of the losing team's sets came from a low position? And that number six on the losing side—the one who dove to save a ball in the back row—no one mentioned that save; had the stands been full, a loud "oooh" would have gone up. But the arena was silent. I saw him drop to one knee, gasping, and no number acknowledged the hope he had just blown into the match. I sat there, pen in hand, wondering: If we cannot count faith, how can we write a sorrow? The answer lies in the structure of the tournament. The national volleyball championship, Vietnam's highest-level playground, has a history of more than twenty years, but only recently has it had regular live broadcasts. Audiences know the national women's team excels at the SEA V.League, winning silver and gold medals consecutively, and know stars like Tran Thi Thanh Thuy and Nguyen Thi Bich Tuyen. But the silent workers of volleyball—a libero guarding a vast territory of first touches, a setter orchestrating tactics—often remain invisible. Volleyball is a continuous tactical battle where one poor dig can kill an entire offensive system. Yet we lack the data to identify where the crack begins. I thought of a match I followed four years ago at a low-tier tournament. A local team with no sponsor defeated the hosts thanks to superb defense. That team was a group of semi-professional players whose tactic was simple: serve to the opponent's weakest area. They won because they had mapped their serves in their heads. The next day, no newspaper mentioned it, because no one had data to prove that comeback was deliberate. People saw the pretty scoreline but not the sweat under the arm of that veteran who served dozens of times without tiring. That is the injustice I want to write about. A volleyball culture that only honors hitters, not setters, loses the credibility of a developing ecosystem. Leading volleyball nations like Brazil, Japan, and the United States spend hundreds of millions of dollars on sports analytics. They can break down every spike, every set, every step into numbers. Vietnam, despite a talented generation and high physical potential, still relies on the coaches' "professional eye." This creates Cold War-era James Bonds who remember every variable but cannot pass it on to the next generation. "Contracts are signed in ink, but understood through countless sleepless nights of the people behind the numbers." I often say this in sports-documentary workshops. This metaphor reflects the reality that every number on the scoreboard comes from the silent coordination of many parts. In Vietnam, however, the very "sleepless nights" of sports data professionals barely exist. There are no specialized schools, no analytics community, and even national teams have to fend for themselves. Based on my experience following the youth teams' matches, I realized that Vietnamese youth-team tactics have barely changed over two decades. They still rely on powerful serves and attacks into the block's hands, but no one seems to measure the effectiveness of each trend. To an analyst, the most dangerous volleyball is "dream setting"—sets that seem improvisational but are the result of a premeditated chain of decisions. To understand this, you must follow every thread of the net and not miss a single mesh. Let me challenge what I say: many in the media believe data is only a game for analysts, that it cannot express humanity or tell stories. I once believed that until the night I watched a goalie sit blankly behind his goal at the 2026 World Cup. In volleyball, however, numbers like a libero's "positive touches" can reveal that she is the team's only shield against a ferocious serve. Without data, she remains a shadow on the court, and people wonder why a losing team keeps a libero they never see doing anything remarkable. On the evening before the match ended, I had brought an old cash register borrowed from a grocery store across from the arena. Each time the number-two setter made a set, I pressed one key; each time the ball arrived at an awkward position, I pressed another. When the match ended, I had a long paper trail of scattered digits. In my hotel room, I decoded it: she set thirty-four times, twenty in the outside attack system, and only three quick sets. But those numbers were not on smartphones, not in live broadcasts, and she remained silent. I called a friend who is deputy editor-in-chief of a sports paper and asked if he would publish a short piece on young setters' metrics. He laughed, saying his readers only care about the national teams at international tournaments and on hitting scores. "No one wants a story about a setter," he said, "because the setter is the hand, not the heart." I knew he was wrong, but I could not convince him. So I wrote in my notebook: 'People do not count the hand, but the hand counts every breath of the match.' Yes, above all, I remain a storyteller, not a statistical machine. I still want to tell of a smile dying before the end of the match. But I want that smile measured by context—by an athlete's actions over a specific time—not by tears brimming in the eye. Because when a player retires, her name will no longer be mentioned. If she has no number to prove she excelled defensively, her arduous journey is erased from history. I left Hung Yen as the arena lights began to fade. An empty court does not erase a match; it only turns an applause into a memory shaped like a player quietly unlacing her shoes. I glanced back at that young setter, standing silently by the bench waiting for the team bus. She did not know that in my notebook, she had become a symbol of the silent laborers of Vietnamese volleyball. People remember a goal, but I remember what happens after the lights go out. And after the lights go out, what remains is a string of unanswered questions, all because of missing data. Who will be the first to approach the workstations of technology engineers to illuminate a national volleyball tracking system? Can the Volleyball Federation of Vietnam order FIVB's analytics suite like other federations, or continue to let coaches remember and forget? And what will we do when an athlete insists she never received a good set, but no one can verify? In the post-data age, if history doesn't record, then heroes don't exist. And I, merely a documentary writer, can do something. I write this as a reminder that the time has come for crying numbers to be spoken. But don't turn me into a stickler for digitization. I want a monitoring system unique to Vietnam, not necessarily the expensive standard. Just a simple app for each team's recorder to mark tempo, set quality, and setter decisions. That many numbers would be enough to change how scouts view the Mekong Delta, where many high-jumping players are being wasted. With just a bit of data, the audience's love of this sport will last longer, because they understand why their team's sets miss their target, and they will be less harsh in defeat, knowing who is doing the quiet work well. We chase transfer news to believe that every wound can be healed with a signature, but soon, let us return to the training ground, where there are no negotiation tables, only sets, and the setter's breath as the ball flies to a spot no one can deny. On a night in a city with no team, I found the greatest match unfolding within myself. That match is called: "The Battle Against Oblivion."
