Lubi Kui (simplified Chinese: 陆费逵; traditional Chinese: 陸費逵; pinyin: Lùbì Kuí, 17 September 1886 – 9 July 1941) was a Chinese educationist and publisher. Lubi (陸費) was his family name. His courtesy name was Bohong (伯鸿). He was an early advocate for simplified Chinese characters.
Lubi was born in a noble family in Hanzhong, Shaanxi, though his parents had come from Zhejiang. His mother was a niece of Li Hongzhang, a famous Chinese politician during the late Qing dynasty. In his early years, Lubi was taught in classical Chinese. Beginning in 1898, he attended to Nanchang English School (南昌英语学塾) and started to learn English and Japanese. He was influenced by new thought and was thus pro-revolutionary.
In the spring of 1903, Lubi went to Wuchang, where he launched the "Xinxuejie Bookstore" (新学界书店). As the manager, he sold many pro-revolution books and booklets. He joined the underground revolution movement and became a surveillant. In 1905 he became the editor-in-chief of the newspaper Chubao (楚报) and after the closure of the newspaper under the pressure of Governor Zhang Zhidong he fled to Shanghai. There, he was employed as the manager and editor of a publishing company. In late 1906, Lubi became the headmaster of Wenming Primary School. He started to make a figure in Shanghai.
