The painting on the wall of the team headquarters in Extreme Challenge Season 4 was mosaic because it had to cover the TV sponsor’s trademark.

When the TV version was broadcast, the TV sponsor's logo was marked, so when the online version was broadcast, the logo was mosaic. After all, it was a TV advertisement, and no money was given in the online version.

"Extreme Challenge Season 4" will premiere on Dragon TV every Sunday at 20:30 from April 29, 2018.

"Extreme Challenge Season 4" is an interactive inspirational experience program launched by Shanghai Dragon TV. The program has 12 episodes. The six fixed members of the fourth season are Huang Bo, Sun Honglei, Huang Lei, Luo Zhixiang, Wang Xun, Zhang Yixing.

The new season will be strongly joined by elites from all walks of life to shorten the distance with the audience with stronger "star quality" interaction.

In the first and second episodes of "Extreme Challenge Season 4", the guests will go back to 1978, and under the leadership of six simple farmers, they will personally experience the large-scale "college entrance examination" . Wearing military coats and big red flowers, the six brothers plunged into a field full of hope, and each had a new identity: Huang Bo became "Huang Tieniu", and Sun Honglei was still "Sun Honglei". Huang Bo said with a smile, "Honglei's name" It belongs to that era!" Huang Lei became "Golden Treasure", Luo Zhixiang became "Luo Tiegen", Wang Xun became "Wang Aijun", and Zhang Yixing became "Zhang Jiashuai".
