Outrageous costumes, cheering, chanting, singing, dancing and, of course, drinking, have all been on display, along with the rugby. It is all part of what makes the Sevens unique. There were even a few “Taylor Swifts” spotted in the crowd.

This is the first time since the pandemic the tournament has enjoyed capacity crowds. Visitors have flown in from all over the world, with overseas ticket sales hitting 42 per cent. It is just what Hong Kong needs.

The city is pursuing “mega events” to attract tourists, improve the economy and rebuild its international image after the pandemic and political changes. But the Sevens was a hit before the term “mega event” was even coined. It quickly grew from humble beginnings in 1976 to become the city’s best-known annual festival.

Fans on Sunday will say an emotional goodbye to Hong Kong Stadium, which has played host to the tournament since 1982.

Next year, the competition will move to the new 50,000-seat Kai Tak Sports Complex. The special Sevens atmosphere must be preserved. A new “South Stand” with unrestricted seating is needed. And the retractable roof should stay open, even if it rains. Maybe a new “Wan Chai” will emerge nearby, to cater for the revellers.

Over the years, the Sevens has had its share of controversy. Some have seen it as an event primarily for expats and visitors, at odds with local culture.

The alcohol-fuelled, anything-goes atmosphere, from booze to boos, does not appeal to everyone. There have been pitch invaders and occasional streakers. But such misdemeanours should not be overstated.

The Hong Kong Tourism Board embraces the spirit of the Sevens, encouraging fans to buy costumes in Pottinger Street, grab a pint in Causeway Bay and attend an “after party” in Lan Kwai Fong.

And Hong Kong China Rugby, as it is now known, has worked hard to grow the popularity of the event within the community, as well as local participation in rugby, while keeping the fun within the bounds of good taste.

Amid all the revelry, it is easy to forget that the Sevens is, at heart, a rugby tournament. The event now forms part of a world series, featuring the top teams, which is reaching its finale. Preparations are under way for the Paris Olympics. There is much at stake.

It is a pity that a format change means the Hong Kong teams are only taking part in a smaller secondary tournament this year.

But fans would have enjoyed seeing both the men and the women seal victory over China on Friday and the women beat Thailand on Saturday.

Hong Kong missed the Sevens badly during the pandemic. The tournament did not take place in 2020 or 2021. It returned in 2022, but with Covid-19 restrictions in place.

Last year, it was back to something approaching its best, spearheading the city’s return to international engagement. The Sevens is expected to boost the economy by HK$320 million. But its value to Hong Kong goes far beyond the income it generates.

The Sevens buzz recalls memories of the freewheeling Hong Kong of years gone by. It is an opportunity for people to be irreverent, humorous, outlandish, noisy, passionate, and perhaps a little wild. There were even cries of “Hong Kong! Add oil!” In these times of political correctness, a little fun is most welcome.

The Hong Kong spirit is often evoked but not clearly defined. Whatever form it takes, the Sevens is very much part of it. It is a key component of the city’s intangible culture. Long may that spirit live on in the iconic event’s new home.
