I am an undergraduate majoring in finance, and I have just been admitted to a postgraduate majoring in finance. I recommend several books, which I have read, and I think are very helpful for me to understand and study finance:

1, Huang Da's Finance (Renmin University of China Press) and Hu Qingkang's Modern Monetary Banking Course (Fudan University Press), these two books can mainly understand monetary banking;

2. Jiang Boke's new edition of International Finance (Fudan University Press) can learn about exchange rates and international financial markets.

3. Zhang Yichun's Financial Marketing, Higher Education Press, can fully understand financial derivatives such as stocks, options and futures.

The above three books are all professional books on finance, but they are not very difficult. If you want to understand from scratch, you can read Man Kun's Microeconomics first, which is easier to understand. Further, Gao Hongye's "Western Economics", including macro and micro parts, is the basic discipline of economics, not only finance, but also economics-related majors.
