The greatest program characteristic of "I Guess" is "youth". The early version of "I Guess" was themed on the opposition between new and old humans. The host, Wu Zongxian, later changed the set, content, and hosting style to appeal to a younger audience, and began to be widely popular among the new generation. Especially in the segments like "Big Revolution in the Brain" and "Guessing Uncommon Idioms", they are excellently designed, interesting, and educational, repeatedly creating viewing peaks, which is quite rare. The producer, despite being young, has a flexible mind that makes "I Guess" unique.
