sound like the taxi in Xian is not expenseive. taxi from terra cotta to hot spring is just CNY15.

If so how much it normally cost if i take
1) cab from XAcity to terra cotta.
2) cab from hot spring back to hotel (Ramada) just estimate and is it convenience to find cab back to town?
B/c if we have 8 pax and take 2 cabs.. price might not be must difference comparing to taking bus and more convenience.

more question on the Mt. Hua Shan.
1) how long and how much for high speed train?
2) how long and how much for the taxi to go from Hua Shan train station(it's called Hua Shan station?) to Mt. Hua Shan?
3) if i take my parents (70+) to Mt. Hua Shan.. they should be able to join us by cable car to west peak, right? is there any more trek for me to go higher and let them wait at the view point after cable for me to get them back?

Thank you!!!
