Since 29 January 2018, she has served as chairwoman of the Zhejiang Provincial Committee of the Chinese People's Political Consultative Conference.
Starting in 1987, Cui began serving at the Tibet division of China Life, where she worked in finance, operations, and motor vehicle insurance.
As an aspiring and relatively young professional, Cui went on to study at the Central Party School in Beijing and earned a political economics graduate degree there.
By July 2002, Cui was named Vice Chairman of the Tibet Autonomous Region, entering the sub-provincial ranks for the first time at 44 years of age.
Her profile was unique because she was a woman of Tibetan heritage; females and ethnic minorities are rarely selected to enter provincial-level standing committees.
