It is important to understand that Yuanyang, in fact, refers to three things. There is Yuanyang County, Yuanyang New City (Nansha), and Yuanyang Old Town (Xinjiezhen). Yuanyang New City is the Yuanyang you will see on most maps and the capital of Yuanyang County, while Yuanyang Old Town is the traditional heart of the county and definitely the location you will be heading if you are a tourist. To make things complicated, if you are in Nansha, then you are in Yuanyang, and Yuangyang Old Town is Xinjiezhen (or simply Xinjie), and if you are in Xinjiezhen, then you are in Yuanyang, and Yuangyang New City is Nansha. Make sure you clarify which Yuanyang you are going to when you hop on a bus. For the sake of continuity, in this article "Yuanyang" will refer to Yuanyang Old Town and "Nansha" will refer to Yuanyang New City.
