She describe her reflection by RIGHT UPSIDE AND SMALLER.
right-side up and smaller
Step-by-step explanation: When you look at the back of the spoon, you see a right upside image of yourself. This is because of the reflective curved surface of the metal acts as a diverging mirror. The back of the spoon act as the convex mirror, then the reflection of the image is right upside and it is smaller.
This image does tend to be distorted because spoons seldom have the spherical or the parabolic curvature. So this makes the image of the Lin Yao looks right upside and smaller.
