Confucius + Han Help

Hey guys so i been playing Civ 7 a lot since TOT update & ended up buying the new expansion pack today… so far loving the game, the only issues is I am entire overwhelmed, and since I am playing on the switch I can’t use add ons…

So I need some help, I have watched a few videos and good openers and right now I am rushing Great Steele + Hanging Gardens, which is a lot of fun to watch snow ball!!

I am playing on immortal so the AI isn’t too aggressive in my experience..

The thing is I am playing Confucius, and going for a science build I’m not exactly sure how..

I don’t need a play by play I just need some pointers, like what should my goals be? How should I be planning.. I have the basics down I just need a plan now..
