The precious calligraphy and paintings left over from ancient my country all have inscriptions and the final signature is the title of the book.
The title of the book is actually the author who signed it with his own name after he finished writing a piece of work, or after he finished painting an entire painting, or he named it on a whim at the time.
The book is to leave your name in your work, as well as the time when the work was completed, so that everyone can easily know who created it.
This question is about an elder writing a few words on a junior’s work to remind the junior. Or a descendant saw the great work of the predecessor during his lifetime, and then wrote an inscription on the work to praise it.
For example, our Qing Dynasty Emperor Qianlong was an emperor who especially liked to put seals and inscriptions on the scrolls of other ancients.
He put two big seals on "Han Xizai's Night Banquet"! After a good picture, he asked him to put two big stamps on it, still in the center.
He also had more than eighty chapters on Wang Xianzhi's "Mid-Autumn Tie", so he, as an emperor, really likes to leave his own footprints on other people's works.
In fact, the inscription is very particular, and it would not be simple without a title. The title of the book means that after the work is completed, you can leave your name and seal to mark it if you are satisfied with it. This work is completed by yourself and no one else can impersonate it.
Generally, book titles are on the left or right. This depends on where the final work will not be obscured by the title, and it also follows the author's habits.
As for the inscription, the author usually finds someone he has a close relationship with, or an elder in the family, or a literary master. The person who inscribes the inscription is very particular.
The inscription is also very particular. The person who gives the inscription cannot write anything casually. The title must be based on the author's content and cannot steal the limelight.
Finally, the inscription should not cover the work as much as possible, so inscribing someone requires a high level of education. If someone takes a work and asks for an inscription, they must write something of a certain standard.
This is the biggest difference between the inscription and the title of the book. One is written by myself and the other is written with help from others. There is no special meaning.
