what would it cost to take a cab from Xian drum tower to the terracotta army museum?

If the cab charges by meter, the fare will be around CNY100~150. However, due to the long-distance, most of drivers may refused to drive you there. In fact, you could take a taxi (CNY15) to Xian Railway Station and then take bus 游5 (CNY7)to Terracotta Warriors Museum directly.
