What are the repayment methods of bonds?

There are two ways to repay bonds: regular repayment and irregular repayment. When the bond matures, the bond issuer buys it at face value. In addition, there are two other ways to repay bonds:

First, the number of bonds is determined by drawing lots, and all bonds are repaid in several batches according to different quantities.

Second, after the issuer buys from the market at the current price, it holds or cancels it. This method is also called buyout repayment. There are also two kinds of bonds that can be repaid irregularly: those with the right of recovery and those with the right of sale.
