Calligraphy has two chapters, one is the famous chapter, and the other is the leisure chapter. What's the use of idle chapters?

Since it is called "idle chapter", it is random, mainly covering the beginning, middle and end of a certain side of the work and the part where the blank of the work increases. Most of the content is poetry, idioms, slang, graphics and so on. After signing, you need to stamp your name, the number is one or two, and the distance is the size of a seal. The position of the last seal is higher than the length of the combined size of the two seals on the bottom line.
