Du Ruhui, courtesy name Keming, posthumously known as Duke Cheng of Lai, was a Chinese official who served as a chancellor under Emperor Taizong in the early Tang dynasty. He and his colleague, Fang Xuanling, were often described as role models for chancellors in imperial China.

Emperor Taizong of Tang, previously Prince of Qin, personal name Li Shimin, was the second emperor of the Tang dynasty of China, ruling from 626 to 649. He is traditionally regarded as a co-founder of the dynasty for his role in encouraging his father Li Yuan to rebel against the Sui dynasty at Jinyang in 617. Taizong subsequently played a pivotal role in defeating several of the dynasty's most dangerous opponents and solidifying its rule over China proper.
