'Mother Peng' devoted to fight against HIV/AIDS

Beyond her title as China's first lady, Peng Liyuan is known for other things, such as being a prominent figure in the fight against HIV/AIDS.

She is the image ambassador of the National Health and Family Planning Commission for control and prevention of HIV/AIDS and tuberculosis and the World Health Organization's ambassador in the fight against the deadly virus.

But for some Chinese children affected by HIV/AIDS, she is simply called "Mother Peng".
