Differences other than price:
1. Is there any difference in copyright?
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.
3. Different packaging covers
The packaging of pirated books is generally bright and the paper is thin.
The packaging arrangement of genuine books is reasonable, and the paper is better and thicker.

Then what should I do? I saw some books (such as photo albums)
