I saw this the other day, and for got to go check out some more of it till you reminded me. It looks like a Chinese person on a long tour of the DPRK, I'm noticing lots of hotels, karaoke and picture taking. I think that Chinese citizens get a lot more leeway when they visit the country, so it's very interesting to see things from their perspective if this is the case.

Edit: a Google Translate of their bio says this exactly (a Chinese person in the DPRK)
