Why is the huge Chinese painting hanging in the old quadrangle in China called "nave"?

Nave, named after hanging on the central wall of the hall, is an upright posture in the mounting of traditional Chinese painting. It is a rectangular work written vertically. The size is generally a whole piece of rice paper (divided into four feet, five feet, six feet, eight feet and so on. ). Because the scale is relatively large, it requires the creator to have a skillful technique and the ability to grasp the layout of the work as a whole. When writing, we should pay attention to the primary and secondary relationship between words and inscriptions, so that they are different in primary and secondary and glow accordingly. Don't steal the host's attention from the guests. The signature can be written at the bottom of the last line of the text, leaving room for layout. Generally, the bottom of a paragraph is not flush with the text to avoid rigidity in form. You can also occupy another line or lines behind the text, and it can't be flush with the text. The seal is smaller than the word "money". Generally, a seal needs to leave more than one word, which can be stamped under the word "money" or on the left side of the word "money".
