I, Chen Mo, retired at the age of 28. I write books and preach about wealth and freedom. On the night of my birthday, a girl in school uniform blocked the door and shouted "Dad!" In front of everyone. She also gave me a cute three-year-old baby who called me grandpa! The whole place was dead silent. I clearly remember that after that night in high school, she said that the child had... Now my daughter is skipping school and looking for me to raise her. The cute baby even took out my biography "Retire at 28". What's even more shocking is that my daughter's class teacher came to visit me, and she was actually the class beauty who made me cry in anger? The cute baby tilted his head and looked at the class beauty, and actually showed my black card: "Mom, dad said he paid for all your hard work." Me: "???" Now, the teacher's fist seems to be harder than in high school. Reading Guide 1. The 28-year-old grandpa is having a great start. 2.
