Feng Yanli, a deputy to the National People's Congress (NPC), has been committed to the independent research and development of new materials for China's aerospace industry for over 20 years, a career that she takes great pride in.

At the No 46 Institute of the Sixth Academy, the China Aerospace Science and Industry Corporation (CASIC), she has been leading a team to develop top-performing F-12 fibers since the 1990s, which are now widely used in aviation, aerospace and civilian industries for their high tensile strength, good sturdiness and light weight.

In earlier research, she overcame great difficulties, such as a lack of reference materials and equipment, and finally achieved success in 2002 after numerous trials and errors. Then in 2008, her team went all out to meet the urgent needs of a key CASIC project and developed three new types of F-12 fibers in just a couple of months. The composite materials' performances have reached world-class level and they have been extensively applied in more fields in China.

As a believer of the saying "no mountain is too high," Feng has devoted herself to the R&D of F-12 fibers, as well as their lab-to-market procedures. Over the years, she has won honors including a second prize at the National Defense Science and Technology Progress Awards and the National March 8th Red-banner Pacesetter.

In assuming the role of an NPC deputy, Feng has submitted more than 20 suggestions to the national legislature, which cover the national defense industry, basic research, protection of women's rights and interests, and educational support for ethnic border regions.

Recently, she was invited by the Supreme People's Procuratorate (SPP) to attend the hearing of a case related to personal information protection, an issue she voiced her suggestions on during the NPC annual session in March. Satisfied with the SPP's response, Feng said she hopes the procuratorial organs exercise their functions in accordance with the law in criminal, civil, administrative and public interest litigations to better meet the people's expectations for the rule of law.
