Normal sudoku rules apply.
Yin-Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected and no 2x2 region is entirely shaded or entirely unshaded.
Circles: The digit in a circle must equal the length of the first run of shaded cells seen along the adjacent row or column. If no shaded cells appear the length is equal to 0. Circles themselves are not part of the Yin-Yang shading.
German Whispers: Adjacent digits on a green line must differ by at least 5 and any digit greater than 5 on a green line must be shaded (excluding circles).

as yin-yang go, this is hard - mitigated by the fact that it's so easy to train anyone to expert level in yin-yang in just a few minutes.
the big difficulty here is that the gws do NOT behave like you would expect.
a MUST SOLVE for any yin-yang fan.

Great puzzle! I had trouble to correctly internalize the rules, so I had to backtrack a lot. That's on me. A very interesting ruleset and satisfying solve, thank you
