What should I do if the hand-painted blue and white porcelain is crooked?

Gently wipe, tilt adjustment, professional repair.

1. Gently wipe: gently wipe the curved blue-and-white pattern with a soft and clean cloth, sometimes it is only dirt or dust on the surface that causes a visual skew.

2. Tilt adjustment: the blue and white patterns are skewed as a whole. You can try to tilt the porcelain slightly and see if you can adjust the visual effect of the pattern. Be careful to avoid other damage.

3. Professional repair: The above methods can't solve the problem. Give the porcelain to a professional art restorer for repair. They have experience and professional tools, which can accurately restore porcelain and restore the blue and white patterns to their original state.
