What is the difference between an investment management company and an investment company?

Investment management companies are mainly engaged in consulting and agent account opening transactions, and most employees only get the basic salary of responsibility, so they will recruit people for a long time, and the long-term recruitment is to develop the market. People who invest in companies move quickly, and those who really stay will generally get good returns. In fact, there is no essential difference between the two, and I hope to adopt them.
