Morphology
up + the + yin-yang
The expression is colloquial/slang and uses 'yin-yang' as a cultural symbol rather than a quantifiable noun, so a learner who knows 'up' and 'yin-yang' would not reliably infer 'in great abundance'. The meaning is idiomatic and construction-specific (similar to other informal intensifiers like 'up the wazoo'), making it non-compositional and unpredictable to a B1 learner without prior exposure.
Etymology
The idiom up the yin-yang may come from the picture of the yin-yang, a small circle with two parts, and the image of stuffing something up into that tiny space. That strong image explains why the phrase means 'a lot' or 'in great excess'.
