'Shí quán shí měi' literally means 'ten complete, ten beautiful' — a classical Chinese idiom expressing absolute perfection, with no flaw or deficiency in any aspect. The repetition of 'ten' (the highest single-digit number in traditional Chinese numerology) emphasizes totality and completeness, while 'quán' (complete/whole) and 'měi' (beautiful/perfect) reinforce the idea of ideal wholeness and excellence.

This phrase is commonly used to describe people, relationships, events, or outcomes that meet exceptionally high standards — such as a wedding, a performance, or a life goal. Though positive and complimentary, it carries a slightly literary or formal tone and is often used hyperbolically rather than literally, since true 'ten-ten perfection' is understood to be rare or even unattainable in reality.
