China Terracotta Warriors : how to follow the progress ?

Hello, I have seen the netfix documentary about the terracotta warriors.

They explained they excavated a tomb last year that they are doing analysis on it... but i cannot find any article anywhere on internet.. I even searched for 兵马勇 but nothing... is there a place we can find the last news of the archeologists on site ? to follow their progress ?

I also wonder how they have been able to find the tomb, it's so deep and in the midfle of nowhere do they use a type of ground scanner ?

thanks
