纯牛奶最纯的牛最纯的奶
[chún niú năi zuì chún de niú zuì chún de năi]
A playful redundancy meant to convey purity, using milk as a metaphor. Essentially, this translates as 'Pure milk from the purest cow makes for the purest milk'. It can be taken to mean seeking or valuing something absolutely unadulterated or pure.
