Young visitors were keen to try timed based activities such as Lu Ban puzzle, with many spending almost an hour in dissembling and rebuilding the structures to win souvenirs. A Lu Ban puzzle, or Lu Ban lock, is a type of toy believed to have been invented 1,800 years ago by Zhuge Liang, who applied master carpenter Lu Ban’s techniques in building mortise-and-tenon joint structures.
The mascots of the 48th WorldSkills Competition hold Lu Ban locks in their hands in a nod to the artisanship of traditional Chinese carpentry.
Isis Poggiolni, a 20-year-old French volunteer, tried more than an hour and solved the Lu Ban puzzle with assistance from the booth staff.
“It’s my first time to play with this toy. I would like to win it as a gift for my 13-year-old brother,” she said. “It’s interesting, pretty complicated, and challenging.”
