Rebirth after the 1950s

Introduction: I am over fifty, childless, taking care of my elderly parents, and after retirement, I have a little money in my hand after my parents passed away, and suddenly a space appears. What else are I thinking about? Hurry up and buy it!purchase!purchase!However, after buying it, nothing happened. I had no choice but to grow old slowly in my hometown.When I opened my eyes again, I found that I was just a little embryo. I didn't know when I was born until I became conscious.From then on, Li Nuan became the life of Li Mianmian and his childhood sweetheart (in the early stage, the parents and the male protagonist’s family were mostly described)
