蘑菇头陪瓜子脸天地一绝
[mó gū tóu péi guā zi liăn tiān dì yī jué]
A playful and creative idiom combining hairstyles (蘑菇 head or 'mushroom head', possibly referring to a style reminiscent of mushroom shape) with face shapes (瓜子脸 or 'sunflower seed face', often describing a slim and oval-shaped face) resulting in 'Mushroom Hair And Walnut Face Match Uniquely' which creates a charming pair of attributes.
