In order to decode a sealed book of saving the world, I started to recall the 47 years of my life experience. I dropped out of junior high school and left my hometown at the age of 20 to find a work in the strange city. When I turned 30, I started my second study life and it turned out to be very long and difficult. I got my teaching certificate and bachelor's degree at the age of 46. Looking back on the past, it was the ordinary people that moved and inspired me the most.
