i want to go to famen temple from xian bell tower.

As I know, there is a shuttle bus at the west gate of Tang Paradise. This bus won’t depart until the seat is full after 08:00. It’s only one bus on the weekdays, while two buses on the weekends. Besides, there are two buses at Chengxi Passenger Transportation Station departing at 09:00 and 16:30 respectively. The ticket fare is CNY37.5/person.
From the Bell Tower to Tang Paradise, you can take bus no.609 at Bell Tower South Bus Stop to Tang Paradise (West Gate) directly.
From the Bell Tower to Chengxi Passenger Transportation Station, you can take bus no.252 at Bell Tower West Bus Stop to the destination directly.
