Tucked into Sonia Pang-Washford's art portfolio is an old black and white photograph. A young Chinese woman with a 1960s hairstyle is sitting among the tall summer grasses of an English field. The photographer - her young English husband - is making her laugh. It is a much-held picture.
'My mother died when I was four,' explained the confident 24-year-old, who was brought up in Kent by her father and stepmother.
'She died very suddenly, and although my father was pretty open in many ways as a parent, it was always difficult for my brother and me to ask him about her.' But now, 20 years later, in a strange way, Pang-Washford has found her mother again - through rediscovering her grandmother and aunts in Hong Kong - and she has put together a show, called Six Of One, Half A Dozen Of The Other, about her experience.
'I always dreamed that one day I would go to Hong Kong and find my Chinese family,' she explained.
She had been saving slowly, through all the years she studied at art school in London, to make a trip to Hong Kong. She had made regular phone calls to the Immigration Department and other government offices to try to find the family members she had not seen since she was three.
'People were quite suspicious; they said it's not my direct family and they could not give out addresses to me.' But, admitted Pang-Washford, the real reason she had not come to Hong Kong earlier was not because she did not have the money or an address to come to.
