X-Tin isn't mix-blood. Look at the curvature of the nose and how concave the eye sockets are. surgery can make ur nose sharper as seen with countless koreans, but u can never make ur eye sockets deeper. dead give away. another tell-tale, the angle of the nose by which is points outwards. her nose points down, not out. disclaimer, this is just my opinion and observation from real mix-bloods in my everyday life. common things in public.
