When an Exhibition Hall Taught Vietnamese Football How to Count a Crowd

On the floor of SECC, people stood in a ring around a lucky wheel. The needle stopped, a corner of the hall applauded, someone cheered. I stood at the edge of that ring — a 59-year-old man in an old coat, a notebook and a waterproof pencil in hand — and I heard a stadium. The applause inside an exhibition hall, if you close your eyes, is identical to the applause on a terrace when the ball hits the net: same rhythm, same pitch, same way people turn to each other to confirm that something has just happened.

I did not go to SECC to buy a home. I went to count.

Three days, eight experience stations, one gift voucher. A problem my trade has been asking for fifty years without ever getting a decent answer: who is keeping the scoreboard, and what is that scoreboard counting?

The event was run by Nam Long Group at the Saigon Exhibition and Convention Center in September 2026, with the final two days falling on 19 and 20 September. Five project brands sat under one roof: Waterpoint, Mizuki Park, Izumi City, Elyse Island and Nam Long II Central Lake. The opening address was given by Nguyen Thanh Huong, Acting CEO of the group. Visitors received an experience card, walked through eight stations, and earned a reward on reaching five or more. The vouchers were worth 50 million VND for high-rise products and 100 million VND for low-rise products, in limited quantity, with value dependent on the specific project and terms. The attached condition: download the Nam Long Living app and check in successfully during the event. The organisers described the crowd as thousands of visitors; the stage featured a lucky wheel, workshops, mini games, and guest appearances on the final two days by Duong Edward, Phuong Vu, Hoang Hai (Bo Gau) and Quoc Thien.

One further detail from that article deserves recording. Buyers were described as asking heavily about location, planning, legal status, construction progress, living environment, financing plans and sales policy. The Acting CEO observed that buyers were becoming increasingly sensitive to legal foundation, delivery capability and the value of the living environment.

Ten years later, writing these lines in March 2036, I understand that what I witnessed at SECC was not a property sales event. It was a funnel. And Vietnamese football learned it faster than I expected.

Let us do the arithmetic the organisers did not publish.

Eight stations, with the reward threshold set at five. Suppose that at each station a visitor has roughly an 85 per cent chance of completing it — a rate that is not low, since most stations require only a few minutes of interaction. On that basis, the chance of completing all eight stations is about 27 per cent. The chance of reaching five or more is close to 98 per cent.

Setting the threshold at five rather than eight is a design decision, and it governs almost the entire emotional register of the event. That threshold does not filter for people who deserve a reward; it guarantees that almost everyone wins. An exhibition where 98 per cent of attendees feel they have just been chosen is an exhibition that does not sell with argument. It sells with the feeling of winning.

The reward, however, does not live there. A voucher worth 50 million or 100 million VND is not cash. It is a conditional discount, limited in quantity, tied to a specific project. The emotion is guaranteed; the cost floats. The organisers separated the two and placed them at opposite ends of a long corridor. At one end, applause. At the other, a reservation contract.

The second calculation is more interesting. The 100 million voucher sounds twice the size of the 50 million one. But if a high-rise apartment is priced at around 3.5 billion VND, then 50 million equals roughly 1.4 per cent of value. If a low-rise product is priced at around 10 billion VND, then 100 million equals roughly 1.0 per cent. The bigger voucher sits on the more expensive product, and the effective discount rate is actually smaller. This is how people who understand their own margins set prices: the figure on the banner doubles, while the concession inside the price structure falls.

The third calculation is the central one. The condition for claiming the voucher is an app download. One app install, plus a phone number, plus behavioural traces from eight stations, plus the answer to which project a visitor cares about and whether they are worried about planning or about progress — that is a data asset. The cost of printing a conditional voucher is far below the cost of buying a genuine app install on the open market. In other words, the voucher is not a gift to the customer; it is how the customer is paid, using the very condition the customer must fulfil to receive it.

Eight stations, threshold of five, conditional voucher, app as gate. That is a four-layer funnel: dwell time, manufactured victory, data capture, deferred cost. People call it an experience event. It is a measurement system disguised as a festival.

Vietnamese football saw the right thing. Over the past decade, V.League clubs have begun rebuilding the supporter journey on the same logic: membership cards replacing single tickets, attendance streaks replacing a single gate scan, and benefits that only activate on renewal. The underlying mechanism is identical: guarantee the emotion, postpone the cost.

Based on my experience of watching matches, this shows up most clearly in stadiums that are full but not returning. Thirty thousand people at one match is a communications achievement. Thirty thousand renewals across a season is a financial achievement. The distance between them is exactly the distance between a lucky wheel and a reservation contract.

Ten years on, what do people remember about the SECC event? They remember thousands of visitors, and they remember the 100 million voucher.

Neither decided anything.

Thousands of visitors is a description with no measurement method, no turnstile count, no independent audit. It sits at the very top of the funnel — the prettiest and cheapest layer to beautify. The only metric that decides whether the event succeeded, the conversion rate from visitor to booking, appears nowhere. An article that boasts about footfall while staying silent on conversion is an article showing off the easy part.

The danger is not the boasting. The danger is that the promises were written down in words: the wheel, the gifts to take home, the celebrities on 19 and 20 September. Every promise written in advance becomes a liability of trust. If the second and third days do not match the page, the loss is not in revenue. It is in people's mouths.

This is where my trade has to speak, because football has repeated this mistake through an instrument with a different name: the loan with an obligation to buy.

Read it the way you read a gift voucher. A small club receives a striker from a big club, free of charge, with an obligation to buy after a number of appearances. At first glance, it is a conditional gift with an easy condition. But an obligation to buy does not function as a discount. It is a price fixed while the market was hot, locked in, and triggered at a moment when the small club no longer has the right to refuse. The emotion arrives immediately; the cost arrives later, precisely one season later.

Meanwhile, the striker their own academy produced sits on the bench for a season, loses value, and is sold at the price of a player who never played. Small clubs go on raising semi-finished products for the giants: they train them, carry the risk, pay the wages, and by the time the product is ripe it belongs to someone else. The 100 million voucher and the obligation-to-buy clause share one architecture: a concession that looks generous, attached to a trigger designed by the stronger party.

At SECC I also noted a small detail nobody repeated. The person who gave the opening address, who laid out the strategic vision, who was the only voice speaking for the group in the entire article, held the title of Acting CEO. In football, we call such a person a caretaker manager. A caretaker can speak beautifully about a five-year plan. He is simply not certain he will be there to sign the third year.

My notebook still holds a few drops of Moscow rain, and beside them, for ten years now, there has been a page about that afternoon at SECC. The two sit together for one reason: both are stories about people standing in great numbers, deeply moved, none of whom held the scoreboard.

At 69, I still believe a beautiful pass is a declaration of love. But I have also learned that a declaration of love is only worth something if the person who made it is still there tomorrow.

The scoreboard cannot capture the heart, and football writes its poetry precisely there. The contract is written somewhere else, in ink with no poetry in it at all.

On an empty pitch at night, I hear the ball breathing. It does not ask how many came today. It asks who will come back next week. If Vietnamese football must build its own funnel — and I believe it must — then let it be built around that question, not around the applause.
