What is the city, and what is the area around - Baoji, Jiangzhang, Fufeng, Shaanxi

I am planning to travel to China, Xi'an and surroundings with my family on holiday and need to know what to search for.
I would like to go to Jiangzhang, Baoji, in Fufeng county, Shaanxi province. But is Jiangzhang a city in Baoji or is it the other way around?

I plan to go by train or bus from Xi'an to Jiangzhang and back again and need to know what to search for.
