A group of Chinese and international artists have joined hands to form a unified identity to touch on the concept of reality during "A Dream Within A Dream", which is running at Tang Contemporary Art until May 3.

The exhibition's title is taken from a poem of the same name written by American poet Edgar Allan Poe in 1849. It is one of his most famous and darkest poems in which he implies the unpredictable contingencies of life and questions if anyone can prevent and control these uncertainties.
