[3] The Concubine's Children documents the story of this family which spanned two continents, as well as the political, social, and cultural tensions in China and Canada, between 1848, when Chan Sam's father, Chong's great grandfather, first came to "Gold Mountain", the nickname by which Chinese people knew North America, and 1987 when Chong and Hing first met the "China family".

[3] Chong was inspired to work on this family history–historical non-fiction novel after moving to Beijing in 1985, with her companion, and later husband, CTV correspondent Roger Smith.

[3] While living in Peking, Denise Chong convinced her mother Hing/Winnie to join her on a three-week trip of China, which would take them to the village of Chang Gar Bin.

Chang Gar Bin was Chan Sam's (Hing/Winnie's father and Denise Chong's grandfather)'s hometown, and the place where Hing's sisters, Ping and Nan, and half-brother Yueng, all of whom she had never met, had been raised.

[6] The book was on the bestseller list of The Globe and Mail for 93 weeks,[6] and was shortlisted for the "Governor-General's Literary Non-Fiction Award".
