Just 5th-grade knowledge, yet not everyone observes carefully enough to solve this tricky Olympia question.
Road to Mount Olympia is the most beloved educational TV program, highly favored on television. Watching the show, besides the suspenseful score comparisons among contestants, viewers also gather quite a lot of knowledge through the challenging tasks and unimaginable questions.
In the 'Destination March - 2nd Quarter Contest', Olympia presents a question: In Vietnamese folklore, this is the proposal of whom to the envoy of the royal court: 'If you return and tell the king to provide me with an iron horse, an iron whip, an iron shield, and an iron armor, I will defeat these invaders'?

Before this question, contestants quickly provided an answer as soon as the MC finished reading it. They answered 'Saint Giong'. However, this answer was incorrect. Later, another contestant pressed the buzzer to contest and also gave the same answer, 'Saint Giong', as the previous contestant.
The correct answer was announced as: THIS PHRASE DOES NOT BELONG TO ANYONE.
Upon hearing the answer, all 4 contestants were surprised, bewildered, not knowing why. MC Ngoc Huy further explained: 'In the double parentheses, one detail was written incorrectly, there is no 'iron shield' at all. Saint Giong's saying only includes an iron horse, an iron whip, and an iron armor.'
MC Khanh Vy then emphasized, Road to Mount Olympia not only tests knowledge but also the carefulness, thoroughness of contestants when reading the questions. This is also a very important skill when contestants enter any competition.

Indeed, a seemingly easy question, within the realm of old knowledge, everyone knows but turns out to be quite tricky!
