1. Punch holes, thread ropes and fasten them with a document binding machine. It is sold in general stationery stores, and it is not expensive. Usually it's only a few hundred dollars. In ancient China, most fields were made by hand. Book binding is the same, only manual binding. At that time, there was no cast iron, and naturally there were no small iron products like binding needles. Ancient books are also hand-made with rice paper, hand-carved, hand-printed, then divided into volumes, punched and threaded, and bound into multiple pages.

2. Use a large stapler, but not as thick as a binding machine. The big stapler is also very convenient. It can be bound with one button and is easy to find. It is also a good tool. However, there are also disadvantages. Ordinary stapler is still not big enough, and it may not be able to order paper thick enough.
