Bai Shouyi (simplified Chinese: 白寿彝; traditional Chinese: 白壽彝; pinyin: Bái Shòuyí; February 1909 – March 21, 2000), also known as Djamal al-Din Bai Shouyi, was a Chinese ethnologist, historian, social activist, and writer who revolutionized recent Chinese historiography and pioneered in relying heavily on scientific excavations and reports. A Marxist philosophically, his studies thus take a very class-centric view and reasoning.Born a son of a Hui merchant in Kaifeng, he became literate in Arabic from his mother and aunt. He died in Beijing at the age of 91.
