How to go from bell tower to Xian Bell tower youth hostel

Around the Bell Tower, there are several bus stations called Bell Tower Stations for different lines of buses.
So would you tell me which bus line you take or you plan to take, so that I can know the exact position of the bus station and tell you how to reach your hotel.
In general, your hotel, on North Street, is close to the east exit of Bell Tower Underpass and very close to the Post Office Building.
