Are there any city buses to the terracotta warriors from central Xian?

Hello, Shakira. I am sorry to tell you that there is no direct bus for the route. My suggestion is that you take a taxi to XA Railway Station from downtown and the taxi fare in the city is not high. Then walk to the east square of the railway station to take tourist bus line 5 (no.306), 914 or 915 to reach the museum. The bus fare is CNY7 per person.
