Nguyen Thi Bien cannot speak Vietnamese properly since she was trafficked to China 28 years ago and virtually lost her mother tongue.
She returned to Vietnam in August after Chinese authorities raided and deported undocumented immigrants. More about how she returned later.
Cut to the present. In a countryside garment factory in the northern Bac Giang Province, Bien sits beside a bunch of red cloth bags.
Around her dozens of other workers are making bags on sewing machines, but not Bien: Her job is to affix the company label on the bags, and she gets less than VND100,000 ($4.32) a day for it.
