Creat a scheme that would allow you to retire at age forty-five.

   Now, in China, the retirement age is depending on the gender and the type of your work. Man who is a mental labor can retire at the age 60. Woman who is a mental labor can retire at the age 55. Man who is a manual labor can retire at the age 50. Woman who is a manual labor can retire at the age 45. So if I want to retire at the age forty-five, I have to do  manual work when I go back to China.
