Early life and education
Li was born into an ethnic Korean family in Mudanjiang, Heilongjiang province in 1965. Her father was an engineer and her mother an accountant.

Upon completing the 11th grade in 1982, she took the National College Entrance Examination a year early, and earned the highest marks in Heilongjiang province. She was admitted to Peking University, where she majored in radio physics. She obtained her bachelor's degree in 1986 and her master's in July 1990.

Career 
In 1990, Li enlisted in the Second Artillery Force, China's strategic missile force. Spurred by the US military's use of information technology in the Gulf War, the Second Artillery initiated an informationization and command automation project in 1992. Li joined the project as its youngest member and was tasked with developing a network framework and a real time data transmission system. In the summer of 1995, the system was successfully tested in a military exercise. It won the People's Liberation Army's Science and Technology Progress Award (Second Class).

After the Iraq War broke out in 2003, the US military again demonstrated the advantage of information technology in battlefield, and the Second Artillery Force decided to develop a mobile command system. Li, who had just been appointed chief engineer of a research institute of the missile force, was put in charge of the project. In 2006, the system passed its test in a military exercise, and the commander of the Second Artillery Force praised Li as being "equal to several brigade commanders combined". The system was awarded the State Science and Technology Progress Award (Second Class).

In 2007, Li proposed the development of China's own command system software, which came into fruition three years later. She also spent six years developing a unified control system for the strategic missile force.

On July 6, 2015, Li was awarded the military rank of major general (shaojiang), the first and only female general in the Second Artillery Force, which became the People's Liberation Army Rocket Force (PLARF) later that year. She currently serves as director of a research institute of the .

Li was a delegate to the 9th and 12th National People's Congress. In January 2018, she became a member of the National Committee of the 13th Chinese People's Political Consultative Conference. In November 2019, she was elected an academician of the Chinese Academy of Engineering.
