Is an ancient Feng Shui book from the Qianlong period of the Qing Dynasty valuable? (with pictures)

No book title? This should be a stone-engraved version, like a book about choosing a date. If it is not available in the world, it may be a little expensive. If there is a book with the same name, it is generally of little value. You can refer to the Confucius Old Books website. The value of ancient books varies. It all depends on the content. If it’s valuable, you don’t have to sell the book; there are many who sell copies.
