1. Online shopping: You can find new books or second-hand books provided by many retailers by searching for titles in online shopping malls, book websites or e-commerce platforms. Be sure to choose a trustworthy seller, check the product description and make sure that the book you bought is exactly what you want.

2. Buy in a physical bookstore: Go to a nearby bookstore, contact the clerk in advance or check the official website to see if it is available and if you can provide the exact version of the book you want to buy. If necessary, you can ask the clerk to order or reserve specific books for you.

3. Second-hand bookstore purchase: Look for the local second-hand bookstore and pay attention to whether there are second-hand books you want to buy. Communicate with the clerk whether the confirmation meets your requirements, check the status of the book and ensure the quality problems.

4. Publishing House Ordering: If you want to buy books from a specific publishing house, the publishing house supports individual direct purchase. You can order a book exactly the same as the current book from the publishing house through its official website or contact information.
