Bond funds can raise funds from the market in the form of pledge through the bonds they hold, and then invest in bonds with the funds obtained from financing, so that the net value ratio of bond funds exceeds 100%. Generally speaking, the net value ratio of bond funds will be limited in the fund contract (in fact, the regulatory system in the current laws and regulations also has restrictions on this). I don't remember exactly what this limit is. It should be around 250% or less.
