Peng Liyuan, the World Health Organization's goodwill ambassador for combating tuberculosis (TB) and HIV/AIDS, recently responded to correspondence from Ma Yu, a professor of the National Center for Tuberculosis Control and Prevention under the Chinese Center for Disease Control and Prevention.

In her reply, Peng said that Ma has been engaged in TB diagnosis and treatment, scientific research and teaching for more than 60 years, and has always been on the front line of TB prevention and treatment, and is still committed to clinical work at the age of 90. Such professional dedication is impressive and admirable.

Peng wrote that as the WHO 's goodwill ambassador for combating TB and HIV/AIDS, she knows that there is a long way to go for TB prevention and treatment. In recent years, the long-term dedication of many medical workers like Ma has contributed to the remarkable progress in TB prevention and treatment. 

She said that she believes that with the government attention and the joint efforts of medical workers and the whole of society, greater achievements will be made in TB prevention and treatment. She would like to continue to work hard with everyone.

In March 2018, Peng as a goodwill ambassador awarded Ma the certificate of "The Most Beautiful Person in Anti-TB Fight".

Not long ago, Ma wrote a letter to thank Peng for her concern and support for TB prevention and treatment, and expressed her determination to continue to apply herself to the goal of ending TB.
