What books have you bought for binding?

I recently bought a novel pill, which is a real paper box. The binding is not gorgeous or expensive, but it feels interesting and has a sense of design. This new pill treats both physical and psychological diseases equally, so you can find all kinds of medicines from foot pain to heartache here. But also conforms to the content, and encourages domestic authors to follow suit and publish a similar book. After all, the design, packaging, publicity and marketing of this book are really good.
