1. The book collection seal can be printed anywhere in the calligraphy work, but it must be in a blank space and do not damage the words in the work. Haven’t you noticed that calligraphy works from a certain era are full of chapters? If you read it carefully, you will find that they are all book seals.
2. The "book" in the collection seal refers to both books and calligraphy works - this is the condensed beauty of Chinese characters!
