When Yao Pingan went up the mountain to collect medicine, he picked up a fool who broke his head. He worked hard, taking care of her as both father and mother for three years, even taking care of her body. As a result, one day, he took Fool to the mountains to collect medicine. Fool fell again and hit his head, but his brain healed. There is just one side effect - that is, Yao Ping'an has been forgotten, and the events of those three years have also been forgotten.
Intention: Don't pick up people randomly when you have nothing to do. Who knows whether it is a blessing or retribution.
