These are the books currently redeemable in the "Points Mall". It is recommended to add some professional books and manuals, such as "Chemical Equipment Process Design" (volume 1 and 2), "Chemical Process Design Manual" (volume 1 and 2), etc.
Oh, do these books need "Haichuan Watermark"?
The metal sticker logo back then was pretty good~~
Never seen it. . . If you don’t do chemical engineering, don’t do research, and don’t make progress, you don’t need it. . . It's just a person in the jar, but it's quite interesting.
Plus some books on exams such as Annotation and Annotation
There is a market for books commonly used in various majors.

Appropriately exchange some paper books to improve everyone's learning * Enthusiasm, many people still like to read the paper version of the book, but the electronic version is tired after reading it for a long time. . . . . .
