[Editor's Picks] Siheyuan: Transmigrating to Build a Strong Nation 【精选】四合院-穿越强国文

I'd like to read something like "I Make Ends Meet by Solving Cases". The protagonist transmigrates into the world of "The Courtyard" and uses foreknowledge or a golden finger to help build up the country! Any theme is fine: becoming an official, joining the military, doing business, contributing technology, and so on! (≧∇≦)/
