The so-called follow-up mechanism refers to the fund company voluntarily paying for a fund under its own banner, or the fund manager is willing to pay for the products it manages.

From a practical point of view, the latter model is more valuable for reference. For example, China Europe Fund requires fund managers to invest their own funds in the fund products they manage, and the proportion of self-investment is as high as 0.55%. In fact, this restraint mechanism requires fund managers to bind their own interests with the fund holders, and truly implement the principle that the fund industry is responsible to the holders based on trust deed.
