travelling in Xian city

I am afraid that one day can not cover all the places you mentioned. From your hotel, you can take bus no. 601 for 11 stops to Tang Paradise, then go to visit the Big Wild Goose Pagoda and the northern square in the morning. Next, you may take bus or taxi to City Wall and ride a bike for a while if you are interested. After that, walk to visit the Bell Tower, Drum Tower and the Great Mosque. The Muslim Street near the mosque is a good place to taste the local snacks. As for the Small Wild Goose Pagoda, it is no need to go there if you visit the Big Wild Goose Pagoda, however, it is not far from the city wall, you can visit it on the way if time permits. It is convenient to travel around the city by public bus or taxi.
