@CitrusArmsSticking a talisman onto Velvet's forehead wouldn't turn her into a jiangshi. In
most lore, jiangshi (chinese hopping vampires) are more closely associated with western "zombies" rather than actual vampires. And even if we do go the route of them just being a subspecies of vampires, it's kinda like... You can't turn a lion into a tiger by painting stripes on it, y'know? They're both big cats, but you can't really transform one into the other. :P
Unless you're like, some kind of horrible ancient eldritch nightmare creature, or a really powerful devil/demon/god. Thenn you could probably perform complete and permanenet body-transformation silliness.
... But this is all pretty much shruggable, since we - again - don't need to follow established (and often-times contradicting) real world lore anyway. ^^;
