Lü Bicheng was a very special woman and a gifted writer in the Late Qing and Early Republican period. The previous scholarships on Lü found her as a poet and an advocate for women's education. This paper goes on to analyze the neglected aspect of her religious life and her influences on the Modern Chinese Buddhist movement. By introducing the international vegetarian movement and animal protection groups in 1930—40's China，Lü helped to bring together the lay Buddhist vegetarian groups and the animal protection movement，consequently promoting the adaptation of international animal protection ideas among the Chinese lay Buddhist activists.
