What is the layering of calligraphy?

Layering, also known as layering, refers to burying branches and vines of plants in a wet substrate, and then cutting them from the mother plant after taking root to form new plants. It is also called paperweight. In fact, ancient people used a lot of auxiliary stationery when writing brush characters. Paperweights, that is, things used to press paper when writing and drawing, are usually rectangular strips, which are also called weight scales and pressure scales for some reason.
