This is the answer to your question:
1, only the name or font size can be engraved, and the stage name is rarely engraved, probably because it is not in line with tradition. Calligraphy is a very traditional art, and we should respect tradition.
The combination of name and font size is rarely done. Because the seal of the name is generally more formal and square. Moreover, the size of the seal is very particular. Generally, the size of the seal is required to be smaller than the signature.
2. Girls may like slim Zhu Wenyin. In calligraphy, seal generally refers to seal cutting. You can choose a finer and more exquisite seal script.
There are not necessarily two. Sometimes, depending on the content of your calligraphy, you need different introductory chapters to highlight the theme of your work (for example, the content of giving people a birthday, such as "longevity for the benevolent", "life is better than Nanshan" and so on. ), so maybe you need a lot. Generally, people who write calligraphy have many seals. There are also some introductory chapters that can be applied to many kinds of works. As for the content of the introductory chapter, you can find one you like online or in books.
One thing to emphasize: there must be at least one famous seal of moderate size.
The location of the seal is also very particular. You can find out about it online or with a teacher.
