Get my father acquitted

When Li Zizhong was withdrawing money, the bank asked him to prove that the owner of the passbook, Li Mu, was his son. However, Li Mu was in the hospital waiting for this money for surgery. At this moment, a group of robbers suddenly broke into the bank. One of the robbers, seeing Li Zizhong's distress, gave him two bundles of money. Li Zizhong used this money to pay for the surgery, but was sentenced to 20 years in prison. It was his son-in-law, Song Zhiming, who put Li Zizhong behind bars.
