My friend Siu Ming and I have been sending letters to each other since he has been imprisoned two years ago, for participating in the pro-democracy protests in Hong Kong in 2019. We share our everyday life situation with each other. We share our dreams and limitations. We tried to talk about the political situation, but the officers censored thoroughly. We learn to read between the lines, and our writing becomes poetic.

Even though I am writing these letters in a country with freedom of expression, staring at the blank paper, I feel the limitations of my own mind. What does mental freedom actually mean? At this moment, we have exchanged around 12 letters.

GPO Box No.211* is a dream-like silent journey, inviting us to a visual reflection on topics such as liberty of mind, isolation and communication through the lens of object theatre. An attempt to keep a friendship alive through the prison walls and across two continents  – even if the distance sometimes seems unbridgeable.
