Tailored services have a good future

On a sunny Saturday four young men and 30 children were seen playing a form of treasure hunt in Jiefang Park in Wuhan, Central China's Hubei province. Divided into four teams, they searched for sequential clues to find hidden messages, instead of prizes. And even though the game took the entire morning to complete, all the boys were happy.

But isn't treasure hunt a game for kids? So what were the young men doing there?

They were providing company to the children - kids' playmates, so to speak.
