Sister B' is a middle-aged Chinese prostitute.
She is often attacked and robbed and her clients frequently don't pay her.
'Sister A' from Jilin looks after a 60-year-old man for bed and board and an occasional handout. She used to work as a nanny for a Chinese family with two children. She was sacked after she collapsed from the gruelling conditions - rising at 5am and working until midnight, six days a week.
But this abuse didn't take place on the mainland. The two women live in France. Their plight is outlined in a report compiled by the Geneva-based International Labour Organisation to highlight the problem of people trafficking from China to Europe.
They are part of a new wave of exploitation of illegal Chinese immigrants in Europe. Over the past five years or so, International Labour Organisation (ILO) legal adviser Gao Yun has been investigating the situation of Chinese trafficked into France, Italy and Britain. She is due to publish her latest findings in May.
But Ms Gao said there were changes appearing in the areas targeted by the trade. Where once Chinese illegal immigrants were dominated by people from Fujian and Zhejiang provinces, increasingly it was middle-aged women from the northeast of China who were fleeing to Europe. Without the strong family networks that Chinese from the southeast have, and with no legal paperwork and unable to speak the local language, Ms Gao said that the women had no choice but to work as illegal domestic helpers within the Chinese community or as prostitutes.
