Siheyuan: I, Qi Tongwei, Take Power in 1960

Qi Tongwei, a soul that should have met its downfall, unexpectedly returned to a courtyard house in 1960.

He became a film projectionist named Xu Damao.

Had the heavens really given him a chance to live again?

And in this life, he had a twenty-year head start over the time he had taken his exams back then.

He decided to climb, one step at a time, all the way to the top.

(Politics is the main focus. You don't need to have read the courtyard-house novels; I'm just borrowing the setting.)
