The Sister I Picked up Has Only 7 Days of Memory

I picked up a little sister in front of my house after get off work. She said she had a strange disease and her memory only lasted seven days, and after seven days she would forget who I was. In order for me to remember her, she gave me the most precious thing on her body - a plastic tie clip. She said, "Brother, this is very hard and can stop bullets." Later, someone offered her 50,000 yuan to buy her life. I threw the card into the ditch in front of him. Because I have hands and feet, even if I have to carry bricks or pick up bottles, I can still afford to support my sister. The farmer uncle saw how pitiful we were and killed his own old hen that laid eggs to make soup for us. Ah Qi's mouth was full of oil after eating, and she said she would marry my uncle and me when we grow up. There are many bad people in this world, but there are always people like uncle, who use their not-so-generous shoulders to protect us from the wind and rain. Don't worry, Ah Qi, no matter how many times you forget, I will tell you over and over again: I am your brother, in this life, the next life, and the next life.
