Runbi refers to "manuscript fee, calligraphy and painting fee".
Moistening brush originally refers to a preparatory action when using a brush, that is, soaking the brush in water. When in use, the bristles are usually soaked in water first, so that the bristles are soaked and softened, so that the writing brush can absorb ink more easily and feel more rounded when writing. In addition, the new pen can also do this before use.
However, with the passage of time, the meaning of "Runbi" has developed and extended. Nowadays, "run pen" generally refers to the remuneration for inviting people to write articles, writing and painting. This custom has always been regarded as a kind of elegance, which provides people with a way to acquire knowledge.
Generally speaking, the brush touch-up is only a preparatory action before calligraphy creation, so that the brush can absorb ink better and enhance the roundness of writing. With the passage of time, the meaning of Runbi has developed into a synonym for the remuneration of literati for writing articles, fonts and paintings, which has also promoted the development of culture and art to a certain extent.

During the Tang and Song Dynasties after the Sui Dynasty, whether in the ruling or opposition, brush embellishment became the default rule. For example, in North Korea, if someone writes an official document or imperial edict in the Imperial Academy, they will get an ornament. In society, those entrusted poets, painters and calligraphers will be touched. This is a very normal thing. You entrust someone else to write an article and draw a picture for you, and you pay some money. This is all natural.
Almost all the great poets in the Tang Dynasty adopted embellishment. I like Han Yu, after all, he is the first of the eight masters in Tang and Song Dynasties. His articles are world-famous. Many princes and nobles asked him to write. Someone is going to publish a book. Please ask Han Yu to write a preface. Someone's relatives and friends died unfortunately. Please write an inscription by Han Yu. Han Yu's embellishment is the highest, and he is known as "the price of a word is like a golden mountain".
