Why are there different traces of bookworm? How do these markings reveal the identity of their tiny creators? Why was the silverfish called "yín" in ancient China? What is the origin of the character qín? What is the connection between the expression dù yú and the famous Tang Dynasty poet Li Bai?

These questions, for a bookworm like me, are like waves relentlessly crashing upon the shore, churning the sea of knowledge just as silverfish stir through the pages. 

The insatiable curiosity, the thrill of discovery, and the relentless pursuit of understanding—these are the very reasons that compelled me to write this book.
