But in general, it is necessary to strengthen supervision and prevent fund-raising or illegal fund-raising with fixed income as the gimmick. For example, in May of 20 16, the CSRC suspended the examination and approval of capital preservation funds, and finally issued the Guiding Opinions on Hedging Strategic Funds in February of 20 17, clearly requiring the name of capital preservation funds and the joint and several liability guarantee mechanism. In this year's "crackdown on illegal securities activities", the CSRC also mentioned that any investment is risky, and it is against the essence of private equity funds for private equity fund managers and private equity fund sales organizations to promise investors that the principal will not be lost or the minimum income will be promised. As Guotai Yuanxin put forward, "it is necessary to ensure the compliance operation and supervision of the whole industry with industry self-discipline and bottom-line supervision".
