This has been bugging me for a while... What is going on with this setting? It appears to be a Korean manhwa, the authors and artists are Korean, lots of character names are Korean (Woon Hyun, Bingseol), the martial arts world is referred to as "murim", several sect names are Korean (Namgoong)... But then there are also lots of Chinese names and locations... Jianghu, Tang clan, Heinan (or whatever the island name was for that southern sea sect), and Woon Hyun had been working in the Forbidden City. And in this chapter, people are wondering "Just who taught the twelfth princess that strange Chinese"?
Is this a murim/jianghu fusion story, set in China?
