What do you call a decorative writing invented by Chinese?

Calligraphy (from Greek: καλλιγραφία) is a visual art related to writing. It is the design and execution of lettering with a pen, ink brush, or other writing instrument.

The term calligraphy, or the art of beautiful handwriting, has its roots and origins in many different countries around the world. It’s most commonly associated with China as that’s where it’s believed to have originated, but different forms were created in various countries around the world including Japan, India, Tibet, and Europe.

Although calligraphy has been around in some form for roughly 3,000 years, the word wasn’t used as a distinction until around the mid-15th century after the introduction of printing in Europe. This was when a clear distinction was created between normal handwriting and more elaborate forms of script writing.
