Lo Pui Man Polly studies the city space she inhabits and explores the possibility of expressing her perceptions and memories of her life experiences. Since she was born in Hong Kong, all inches of soil have been turning upside down due to extensive construction in the recent half-century. That is to say, she moved around the city and resided in an unsettled place. The debris left on the renovation site is sentimental to remind the ageing, replacement, and elimination. And also, the fading of familiar landmarks. So, Lo synthesises her collected images that allow her the process of searching for the phenomenon of tangible and virtual in her being.
