A group of singers wearing solemn black suits as well as cat-ear hairpins look at the camera seriously.

Are they about to perform some serious classical music?

Not exactly!

If you listen carefully, you may be surprised not only by the lyrics to the song and but the animal noises made for fun throughout the performance.

This is a song called So far, the sofa is so far, meaning "I am worn out because of too much work" in Chinese, which has become a new internet hit overnight.

Since it was released on the social network Sina Weibo on July 27, it has received a high click-through rate of 3 million within 7 hours.

The song has daily Beijing life as a backdrop with a focus on complaints about overtime work among office workers.

The song is performed by Shanghai Rainbow Indoor Chorus, a band established by students from the conducting department of Shanghai Conservatory of Music in 2010.

With an average age of 24, the band consists of young people from all walks of life ranging from programmers, designers, accountants to graduate students of anthropology, chemistry and gourmet food.
