In the first episode of the documentary's new season, the couple return to an indigenous tribe living deep in the Amazon rainforest that they had visited previously, to see how the COVID-19 pandemic has affected the life of the population of the tribe, which remains relatively isolated from the outside world.

The couple have been to more than 100 countries and regions and have become renowned global adventurers. They are often offered opportunities to attend international meetings on education, which inspires them to do more for the children growing up in their motherland.

Zhang says they are going to launch an educational base where students can be equipped with outdoor skills that might help them survive in extreme environments, as well as the ability to deal with emergencies, such as a fire.

The show's release on Mango TV is also a move for the platform to enhance its international communication capacity. In March 2018, the platform launched the international version of its mobile app, which offers services in 18 languages to more than 195 countries and regions around the world. Currently, the app has garnered more than 109 million foreign users. Additionally, Mango TV's official channel on YouTube has attracted more than 17.2 million subscribers.

"Art is the universal language. And pop culture is more likely to be spread among the masses than other sorts of culture," says Gong Zhengwen, president of Hunan Broadcasting System, to which Mango TV is affiliated. "And the image of Chinese people, such as Zhang and Liang, can be fully presented to the world through cultural products of varied forms."
