But Yiu admitted he needed to determine whether his body could withstand the rigours of an Olympic Games campaign, with Hong Kong set to try to book a Paris 2024 spot at November’s Asian qualification competition in Japan.

The winger was also planning to talk to his wife, who is due to give birth to the couple’s first child in December, before reaching a final decision over his rugby future.

“The Olympics has always been my dream, and I hope I can achieve it,” Yiu told the Post, soon after landing at Hong Kong International Airport on Wednesday.

“My two concerns are my family and my body – they are what could make me retire. I don’t know if my body is ready to go again.

“I can’t say, ‘I am OK, let’s go for it’, just because it is my dream. I have to think about the team, if I am not ready, they will suffer.

“And my baby is coming soon, we are quite nervous, so I have to talk to my wife and my family about what is right for us.

“I will take a week off, then ask myself if my body is OK, and talk to the coaches and physios, then decide. It is one of the biggest decisions of my life.”

Yiu began his Asian Games by joining wushu’s Mok in leading Hong Kong’s team into a cacophonous Hangzhou Olympic Sports Centre Stadium on opening night.

It was some introduction to opening ceremonies for flag-bearer Yiu, who did not attend the occasions, nor the closing ceremonies, at the past three Games.

“Oh my God, that moment, representing the whole of Hong Kong, and Hong Kong athletes, it was amazing,” Yiu said.

“When I got in the tunnel, I was so nervous. To hold the flag and come into the stadium, the feeling was the same as running from the tunnel in the Hong Kong Sevens, with your heart thumping and the crowd chanting, ‘Hong Kong’, over and over.”

Yiu classed Hong Kong’s semi-final victory over Japan, after trailing until the closing seconds, as “one of the most significant” of his 14-year international career, given the manner in which it was achieved and its proximity to Olympic qualifying.

“I never thought the game was lost, we trust the system and trust in ourselves that we can perform under pressure,” Yiu said.

“It is a big change for us … that we can beat the pressure. Maybe, in past years, we wouldn’t have been able to do it.

“We will use that game to motivate us for the Olympic qualifiers, it was very important for us.”

Yiu “stretched and listened to relaxing music” to recover from the elation of beating Japan, in time for the final against South Korea, which Hong Kong won 14-7 – before celebrating by “getting stuck into” unlimited KFC available in the athletes’ village.

“If that feeling of excitement [after defeating Japan] had continued, we’d have lost the final,” Yiu added.

“We did the recovery and analysis and the coaches told us to use the result to motivate us in the final.

“This medal is very meaningful for me, and being flag bearer made it even more special. Winning two successive gold medals is history making. I am very happy with that ending in the Asian Games and I am going to enjoy the moment.”
