When she was about 7, Isabel was sold into domestic servitude to a wealthy Taiwan family who later moved to California. She endured a childhood of constant work and beatings and only escaped when she was in her 20s.
CNN's Martin Savidge first talked to Isabel about her story in November. In that conversation, Isabel said her wish was to be reunited with her mother. "If I find her I say Mom I love you so much. I still want to find you," she said.
Her story sparked a media storm in Taiwan and the country's foreign minister helped locate Isabel's family.
On Thursday, after 20 years, Isabel got her wish and was finally reunited with her mother. Watch more in the video above of the mother and daughter meeting for the first time after decades.
