Yin is within Yang, not opposite to Yang. Taiyang Taiyin

It is about the struggle of opposites between Yin and Yang, their interdependence, mutual roots and changes. The so-called yang has yin and yin has yang. It should be regarded as moving rather than static, interdependent rather than antagonistic.

A thing has both yin and yang, and the "yang" of yin in yang refers to this thing, not just the yang of yin and yang. The sun and the moon refer to the changes of yin and yang.
