Luowenyu is in Zunhua, and very convenient to get to. Only 9 kilometers from the bus station, you can just wave for bus number 1 (there are no bus stops for bus 1) and take it to the end station and arrive there in fifteen minutes.
There are, as far as I can tell, three sections I can see – this wall is cut through by roads at least twice. I only walked up the middle section between the roads.
