Memories of 31 June 1997 is a looped video which presents a slow-motion transit of the space between the Hong Kong and Shenzhen immigration points of the Hong Kong , Mainland China internal border. We have already left Hong Kong when the video starts but we never arrive in China even though the video is over an hour and a quarter in length. The soundtrack for this video features a collection of oral history interviews conducted with people concerning their memories of 31 June 1997, a non-existent day between the end of British sovereignty over Hong Kong on 30 June 1997 and the beginning of Chinese sovereignty on 1 July 1997. Around fifty people were interviewed over a period of several years (beginning in 2013). These anonymous interviewees all have some connection to Hong Kong but not all of them were in Hong Kong at the time in question.
