From what I remember, one of the senior elders of the Tang Clan. Chung Myung knows them, but I’m unsure if the elder recognizes him.
Yees one of elders of Tang Family recognized him, Chung myung died in the past while that elder is still a child, he often played with Chung myung and Tang Bo, but in the present the Elder is suffering in some kind of dementia or being senioe that's why even though he really recognize Chung Myung they pass it as him having episodes, but at one point he recognized that Chung myung got reincarnated, but kept it a secret and goes back to his old self.
It's when Chung myung asked for swords and the best blacksmith is that elder.
Isn't there anyone from other sects or families that are still alive? Or like a rejuvenated master or something? I really want someone that knows him to react seeing a copycat version of him without knowing that it's actually him, that'll be funny.
