You have to spend 9, 19 to buy a financial business class, not counting IQ tax. You have some basic financial knowledge, either from the popular financial books such as Rich Dad and Poor Dad, Qian Qian the Dog, The Road to Financial Freedom, or some basic financial knowledge: what is a fund, how to make a fixed investment, what is financial management, what financial products are available, how to stock up, and so on. These are all common sense information. It's normal for you not to study and spend some money, but you don't need much money. 100 or 200 at most is enough.

However, if you want to make a fortune from such a course after reading the advertisement, and you don't have the money to pay thousands or tens of thousands to go to school through online loans, credit cards, installment payments or borrowing money, it is really an IQ tax.

The contents of all financial and business courses on the market can basically be found in various financial books, and these books are relatively comprehensive and systematic. After reading a few good books carefully, you can basically understand all the knowledge, and it doesn't cost much. Dozens or 100 or 200 yuan is enough. But if you don't have reading habits or want to save time and energy, spending a little money on financial and business courses is not an IQ tax.
