how do i get from bejing to the terra cotta warriors?

From BJ, you fly or take trains to reach Xian first. At the east part of Xian Railway Station Square, you can find the direct bus Tourism Bus Line 5 (306) in green to reach the Terra Cotta Warriors directly.
From the airport to the railway station station, the airport shuttle bus line 2 can take you to reach.
If you take the ordinary trains, get out of the railway station, you can see the square.
If you take the bullet trains, you can take the subway line 2 to reach Beidajie Station and then take a taxi to reach that square.
