After the variety show Super Brain was broadcast in the seventh season, Song Jiachang won the love of countless fans with his high emotional intelligence, especially his warm smile. In addition, his gentleman and warm heart left a deep impression on female fans, which was really amazing.

In the ninth season, Super Brain aims at the investigation of high-order thinking, upgrading from "six dimensions in plane" to "three-dimensional nine-dimensional investigation model -Level-K", adding three dimensions: decision-making breadth, cognitive height and thinking depth. "K" not only represents the highest dimension, but also represents the highest thinker, which is the core and brain power of this season.
