Xian terra-cotta warrior & Huaqing Hot Spring

Of course, there is. At the east square of Xian Railway Station, you could take city-bus 游5(306) to the Terra-cotta Warriors directly. The bus also has a stop at Huaqing Hot Spring on the way. Usually, it is suggested that you visit the hot spring and then proceed to the terra-cotta by 游5(306) or any other local city-bus. When the tour ends, you could take the same bus back to downtown Xian directly.

Thanks for your advise. By the way, may i know why it is suggested to visit Huaqing hot spring then only terra-cotta? In addition, is it worth to visit 秦陵地宫?

Well, you could have a brief view at the tomb. Currently, you should purchase a connection ticket which includes the entrance fee to the Terra-cotta warrior and the tomb.
