Differences other than price:

1, whether the copyright is different.

Pirated books have no copyright, which is illegal and infringes the copyright of others.

Genuine books are legal and have relevant authorization.

2, the handwriting clarity is different.

Pirated books are scrawled and muddy, and some fonts are illegible, which affects reading.

Real books are clear and readable.

Pirated books refer to books published without the authorization of the original author or publisher. Pirated books generally have bright cover colors and muddy handwriting. The cover paper is thin and the offset glue overflows. Pirated books can be judged from many aspects, and the harm of pirated books is countless.

Look at the cover first, which can be observed from the aspects of color, clarity, cover paper quality, book paper quality, book binding and so on.

There are actually many aspects. For example, whether the font size of chapter titles is uniform, whether the handwriting is clear, and whether the book block paper is suspiciously thin (except dictionaries and art books, most book blocks use about 55 grams of writing paper).

There are also some photocopied pirated books. Although there are no typos, it is inevitable that the typesetting density is inconsistent or the distance between the head and the foot is not uniform. Of course, there is a pirated book called high imitation, which is exactly the same as printed genuine books. Generally, this kind of book will not be very popular in the market, and the booksellers will directly supply it to major trainings.
