Founded by Yi Wang, Hui Lin and Ben Hu in 2012, Liulishuo is the world's leading "AI + Education" company. The Company has developed the world's first 'AI English Teacher' based on deep learning, which provides a personalized and adaptive learning path for every learner.

After years of accumulation, Liulishuo now has the world's largest database of Chinese speaking English. On this basis, the company independently developed the world's first multi-dimensional, multi-granularity auto scoring engine and adaptive learning system to provide users with a complete set of English learning solutions covering listening, speaking, reading, and writing. The Company's flagship mobile app product "英语流利说" has more than 60 million registered users and over 600K paid users, from 379 cities in China and over 175 countries around the world.
