Preface
In this life, how many ten years can one spend as he pleases?
Shen Xi slightly felt that there were three.
The first ten years were ignorant and naive.
In the second decade, youth has no regrets.
In the third decade, life is trivial.
After the age of forty, there are no more troubles.
"I want to think about it since I was young, all the way to the age of seventy."
If you can let me accompany you until ancient times, even if I just watch you silently from behind for all the ten years, there will be no complaints, right?
