What books should I use for the second semester of the second year of the Department of 6 of Harbin Institute of Technology for analog electronics and basic mechanics? What do I learn in the basic mechanics? Is it drawing?

The books for analog electronics and mechanics are published by ourselves. The one for analog electronics has a blue cover and is edited by Wang Shujuan, and the one for mechanics has a red cover. There are not many drawings, but mechanics is divided into two semesters to complete the book. Sometimes there will be big assignments, so you will have to use a few large drawings. But just say the large drawing is No. 3 drawing. At the end of the first semester of your junior year (a few days ago), there will be a course design that will make you draw until you vomit blood. Apart from that, there is nothing to draw. It is not easy to make questions on the basics of mechanics, so I wish you good luck.

Who has the syllabus for the electrical engineering postgraduate entrance examination at Harbin Institute of Technology?

Regarding the syllabus, one is 827 and the other is 826. One contains digital electronics and circuits, and the other contains analog electronics and digital electronics. If you are taking the electrical engineering exam, you need to look at the one about digital electronics and circuits. If you are taking the instrument science exam, you need to look at the one about digital electronics and analog electronics.
