"At first, we found it hard to persuade them when we have divided opinions about the styles of songs in the variety show. For example, they tried to adapt classic songs in an innovative way, but we were worried whether viewers will like the style or not," he says.

Then Fan chose to fully trust them in their expertise－they are in charge of choosing and adapting songs. For example, the adapted version of Xuancaohua, which literally means "day lilies" in Chinese. It's a song about the greatness of motherly love, and became popular on social media.

"It turns out that they know the taste of the audience well. Good songs will always resonate. Professional people do professional things－that's what viewers want to watch," Fan says.

"Many musicians may propagate an air of cool aloofness, but their inner world is fun and humorous. For example, rock 'n' roll legend Zhang Chu has become more open about himself as the variety show goes on. He is showing us an unpolished version of himself and has become popular online."

Participants will not be eliminated during the filming. Instead, some well-coordinated groups will be reshuffled so they have the opportunity to cooperate with different musicians, even if sometimes, they are reluctant to part with previous partners.

"In the end, a few participants of different genres team up with each other and figure out how to gel. It's also a way to inspire their creativity," says chief producer Wu Tong.
