Cui Sun (崔損) (died November 27, 803[1]), courtesy name Zhiwu (至無), was an official of the Chinese Tang dynasty, serving as a chancellor during the reign of Emperor Dezong.
[2][3] Toward the end of Emperor Daizong's Dali era (766–779), Cui Sun passed the imperial examinations and was made a scribe at the archival bureau.
However, later, because his maternal uncle Wang Hong (王翃) was the mayor of Jingzhao Municipality and thus could not properly serve as his superior, Cui was made a Dali Pingshi (大理評事), a judge at the supreme court (大理寺).
He later became You Jianyi Daifu (右諫議大夫), a high-level consultant at the legislative bureau of government (中書省, Zhongshu Sheng) in 795.
He was also criticized for not expanding the tomb of his mother and not attending the funeral of his older sister (who had become a Buddhist nun).
