I went to the bank to withdraw the 20,000 yuan left by my deceased father, and the teller insisted on me proving that my father was my father. I broke my leg while running, but I didn't prove it. Three months later, the same bank and the same teller confidently informed me that I would repay a loan of one million yuan for my father. I looked at them and smiled. Yes, but you have to prove first that I am my father's son. This time, it's my turn to teach them a lesson.
