Non-standard products are non-standardized products. Like p2p online lending, private equity funds can also be said to be non-standard wealth management products, while national standard wealth management products are relatively standardized. Non-standard wealth management products bypass the bank or bond approval department and directly connect the investment and financing parties through a non-standard carrier. In the past, non-standard financing parties were mainly mining and manufacturing enterprises, but now p2p financing platforms and private equity funds are the main ones.

From the perspective of investment alone, there are certain investment thresholds and certain hidden dangers in security.
