Does shaoyin belong to yin or yang in Zhouyi? Is shaoyang yin or yang?

Hexagrams are derived from the bottom up. Taiji gives birth to two devices, one yin and one yang, the horizontal symbol is yang, and the broken symbol is yin. Adding a yang on the horizontal symbol is the sun, and adding a yin on the horizontal symbol is the lack of yin (although his name is less yin, he is yang-born, but a yin is added on the basis of yang, because yin is yang-born, so yang is old and yin is less, so it is called less yin and less yin. Adding a yin at the break is Taiyin, and adding a yang at the break is Shaoyang, which belongs to Yin.

Attach pictures from ancient books.

The black square represents yin and the white square represents yang. Add a black square on the white square, that is, the bottom is broken. It is clearly written in the book that this is called Shaoyin.
