Regular script, known as Kai Shu in Chinese, is a standardized style of writing used in modern Chinese calligraphy. It emerged during the Sui Dynasty and became widely adopted in the Tang Dynasty. This script is characterized by its clear and legible strokes, making it suitable for both print and handwriting. Regular script is the most common form of Chinese characters used today, serving as the foundation for learning and communication. It consists of well-defined characters that are easy to read, which helps in preserving the meaning and structure of the language across various contexts.
