Handwriting, which has evolved over aeons, is receiving a tech edge in China from the boom in artificial intelligence or AI-enabled educational services.

Thanks to the rapid advances in image-recognition technologies, emerging smart hardware is reshaping how China's 188 million pupils will write and interact with teachers.

T-One, an AI-enabled smart pen, can instantly digitalize students' handwritten notes, automatically evaluating their answers, potentially reducing the workload of both teachers and students.
