Many young people may be inspired by a choir of elderly singers and their jovial performance. With an average age of 75, the choir, made up of alumni of the prestigious Tsinghua University, has become popular online, thanks to its performance on last year's web gala.

Clad in dresses, shirts and bow ties, while swaying to the music, their unique interpretation of the popular song Adolescents attracted billions of views.

They are expected to surprise the audience again this year. An upgraded version of the song will be accompanied by the Shanghai City Symphony Orchestra.

Mi Weimin, the choir's conductor, says the choir gave him a chance to demonstrate his passion for music and life.

"Though it takes me four hours or more each time to coordinate members and rehearse the song, I can feel a sense of achievement, and that's what keeps me going," Mi says.

However, some choir members expressed concern about their performances this time, as their previous one had achieved unexpected success.

"I'm not sure if the audience will like this show. What we can do is to try our best and be open to feedback," says Mi, adding that he is happy the elderly are being offered a stage to contribute to society in their own way.
