I lived in Henan - 4 hours by train from Luoyang. Luoyang is an ok place to be, but nothing special. It does have the grottoes and Shaolong temple not far away, which is nice if people visit. As for a city, it's fairy standard. Not great air quality as a whole. Not much in the way of parkland. A charming little system of trams ran around the place.
I could live there.
