Although bond funds do not trade on holidays, bond funds mainly invest in bonds and will still generate interest income during the Spring Festival. This is because the essence of a bond is an "IOU" to repay the principal and interest after the agreed time limit, so the interest of the bond is calculated every day and will not stop because of holidays.

In addition, if bond funds invest in other assets such as stocks, these assets may also generate gains or losses during the Spring Festival, but this situation is relatively rare.
