Because finance is a broad concept, it involves many industries in practice, such as banking, insurance, securities, trust and so on. If you really want to know, you need to go to specific industries to master relevant knowledge in depth. If you just want to know some concepts, you can read some books on financial popularization, such as a book called Understanding Finance and Graphic Finance, or you can read some non-textbook books by famous scholars, such as Tang Ya's Money Never Sleeps and Chen Zhiwu's The Logic of Finance. If you are interested in reading textbooks, you can recommend mishkin's Monetary Finance and Man Kun's Principles of Economics. If you just want to know about finance, crowdfunding and investment, there are separate popular science books, such as Learning Crowdfunding from scratch, Reading Financial Report in a Book, Financial Report as a Story Book, and The easiest thing to invest.
