Speaking about the performance, Fu Han, the lead vocalist and songwriter of the band, says: "When I was a child, I believed I had superpowers. But as I grew up, I was disappointed that I did not have such powers. But we get inspired in our lives, and superpowers still exist in our imaginations."

As for the bus show, she says: "I guess we are the first band in China to perform in a moving vehicle. It was fun and exciting. The stage is everywhere. It's a space with a special energy - a superpower."

Looking ahead, Zhang, who has worked with top singers such as Faye Wong, Li Yuchun and Xu Wei since the 1990s, says that he is glad that he is still making music, and adds that he gets inspired by things around him as well as photography, films and paintings.

"It's not easy to focus on only one thing. So, I took up this project because it takes music back to people - those who listen to our work.

"And, it gives me, as well as the singers and the bands participating in the project, clear feedback about how the music has an impact on people. It keeps me going."
