As a member of the Yi ethnic group, she couldn't speak Mandarin - the standard national language. Even the train tickets were purchased with the help from fellow villagers.

Bamu spent her childhood on a high mountain. Though a school was down the mountain, it took two hours to walk down. So, like many other local girls, Bamu has never been to school.

While working in the factory, she practiced speaking Mandarin and tried to integrate into an unfamiliar society.

During her working days in Nanchang, the biggest headache for Bamu was her second daughter's illness. Back at home, she would take the girl to a hospital in the nearby town. But in the new city, she did not know how to go to the hospital. And she was forced to go home to seek treatment for the girl.

The famous photo taken at the Nanchang railway station in 2010 recorded the moment when Bamu went back home with her second daughter.
