Linked there is a modern take on an ancient form of stored writing in China. In the west written text was carved into stones (giving us the runes) or written on scraped animal hides (vellum, before the technology of paper arrived in Europe). In Egypt it was a form of proto-paper in the form of papyrus; this kind of technology for storing writing was replicated in other places using similar reeds until paper itself was invented.
But in China writing was stored on slats of bamboo that had words painted onto them. This informed the style of writing (Chinese writing is very dense: side-by-side translations of Chinese to English often have the Chinese side with 50% larger font sizes or more and still occupying far less space than the English side!), and also why writing was done top down. The written form shaped the storage technology which shaped the written form in a tight spiral.
One way to do world-building is to look at how other cultures did things differently than the west and do some modified form of the same thing. It gives a lot of otherness to the flavour and can help immerse players in a different fiction world.
