There are many kinds of calligraphy seals, such as famous seal, fast seal and idle seal. Generally, the signature name is stamped with the name stamp, and the space can be stamped with the Zhai Hao stamp. In order to make the book echo up and down, the first seal is often stamped on the upper right of the book, also called the first seal. The content of the beginner's leisure seal can be selected from "learning the sea", "seeking" and "learning books".
What you mean by ink margin, keeping gold and auspicious opening, should be idle chapters, sometimes used as corner seals, which are mostly in line with the author's personality and interest, but you can't see the painter's name only by idle chapters, depending on the name seal.
