It's possible that:
* There's a misspelling. Perhaps you meant a different name? Can you double-check the spelling?
* It's a less-known author. If this is a unique or less-common name, finding information might be challenging. You could try searching online using specific keywords, like "author Ru Pu" along with any other details you know.
* It's a pseudonym. Some authors use pseudonyms, so the real name might be different.
Please provide more context or clarify the name, and I'll do my best to help you find the author's works.
