Following up on my previous puzzle, find here a second puzzle with the same rules.

Rules:

• Normal Sashigane rules apply:
  Divide the grid into regions of orthogonally connected cells (representing Sashigane, a Japanese carpenter's square). Each region must be an L shape with a width of one cell. Arrows must lie at one end of an L and point toward the bend. Circles must lie at the bend of an L, and if one contains a number, the L inside must contain the indicated amount of cells.
• Additionally, shade some Sashigane (the whole L-shaped region must either be fully shaded or unshaded) such that the shaded and unshaded cells form a Yin-Yang pattern:
  • All shaded cells and all unshaded cells must be orthogonally connected.
  • No 2x2 region may be fully shaded or unshaded.
