Chinese cursive script developed from the more formal regular script ("kaishu" in Mandarin) and is often used for quick writing or personal correspondence. It requires a high level of skill and familiarity with the Chinese language and characters, as it involves simplifying and connecting strokes in ways that may not be immediately recognizable to someone unfamiliar with the style.
Chinese cursive script is considered an art form in itself, and it is admired for its expressive quality, dynamic brushwork, and the challenge it poses to both calligraphers and readers.
