Wang Hengyi, the youngest challenger of "Challenge Impossible", launched the "Jiugongge" challenge in Tang poetry. The judges randomly selected 10 poems from 300 Tang poems, and randomly selected 9 words from two couplets and put them into Jiugongge. For Wang Hengyi, who is only five years old, it is not easy to identify poems with only clues when every word flashes out of order.
