Rio 2016: A marriage proposal at the Olympics medal ceremony

There are dramatic marriage proposals - and then there's proposing during the biggest sporting competition in the world.

Chinese diver He Zi had just received a silver medal for the women's three-metre springboard at the Rio Olympics on Sunday.

But she ended up with another prize when her boyfriend Qin Kai, in front of a global TV audience, went down on one knee.

Luckily for Qin, who himself won bronze in the men's three-metre synchronised springboard last week, He Zi said yes.

"We've been dating for six years, but I didn't expect him to propose today," she said. "He said a lot of things, made a lot of promises, but I think the thing that touched me the most is I think this is the guy I can trust for the rest of my life.

But some viewers have suggested that his shock proposal stole the limelight from her other precious metal, her Olympic medal.

Why do some people propose in public?

This is what happened to He Zi, who, when faced with the little red velvet box, is overwhelmed and wipes tears from her eyes.

It lasts just a few moments but Qin Kai appears unable to bear the anticipation...

But the gesture has divided audiences. On the BBC's Facebook page, some users say that his proposal upstaged the glory of her medal win, while others say it merely added to her medal tally.

It's one of the biggest trends on China's Twitter-like Weibo service with some calling it "sweet and romantic" but others weighing in with more scepticism: "What a way to add pressure to her, having the entire world watch her as she makes such a private and life-changing decision".
