Russian Refugees in Hong Kong

Russian Refugees in Hong Kong
The two smallest children are the host's. It was taken at the TST YMCA in Hong Kong. The blonde Russian girl and my Eurasian Chinese/Russian mother (Leah Gershevich) came from Urumchi, Xinjiang, China. Their family settled in Auckland, New Zealand whereas ours went further south to Christchurch. Does anyone recognise this photo and the people within it? See other photos for further details.
