You can do it in the neighborhood Committee where your hukou is located (you put it in Yulong), and you can get a marriage certificate or a single certificate. Bring your household registration book, ID card and one-inch and two-inch photos (different places are different). I remember there are two two-inch photos, which cost a little.
What's the difference between being married and being single? Anyway, you are alone, hehe.
