A Cage for Whom questions human's empowerment of time through idealised rhythm. The artwork grounds Zhao Jiajing's increasing disbelieve in modern time-keeping system, which has been developed to create a dimension of rhythm superior to the nature. As a result , the time as a continuum has been annihilated to regulatable units.

The artwork provides a interactive sonic experience of empowerment. With a clap, the audience can reset a mess of found clock sounds back to synchronised. Following the idea of regulating time, the artist developed a set of physical installation with Cages, mesh, and antique clock parts.
