The first one is called information transaction. They sell trading information, recommend investment projects to you, and enter and exit warehouses. You may or may not listen, and you may not buy it. No, both parties must abide by the confidentiality agreement. They test you to buy their trading information to make money.
The second is called trust investment. They are responsible for managing your investment. They operate and earn dividends together, and no one bears the burden. You only have the right to recover the funds, not the right to control what they invest. They make money from your investment.
In fact, these two kinds of investments are legal, but they are in the gray area of the law, because there is no legislation on them yet, only established provisions. There is no formal supervision department and organization, which does not belong to the jurisdiction of the CSRC or the Administration for Industry and Commerce (the business content is right or wrong). And there is no way to complain to the Consumer Protection Association, because he told you that this story is risky and you should be cautious when entering the market. He will tell you that you will not make a steady profit 100%.
First, they usually make you money, but compensation will make you lose everything. They are often the black hands of bookmakers to fool retail investors.
The second type is relatively stable, and it is generally done by large companies. Their company is supervised by the CSRC and all the CIRC.
I know a few people who do Ping An Trust. The company is absolutely good, China First Insurance Company. Regulators can also be linked.
I also stayed in the first organization, because of the boss's problem, I couldn't keep my customers, and finally the company closed down.
However, both of these things require you to have absolutely enough industry knowledge to get in touch with them. Otherwise, it is as easy for the industry to deceive the outside world as it is for kindergarten children.
