Give an example to explain what is called "Yin people blocking" in metaphysics.

Yin people, that is, Yin Qi-chong's people, usually do Yin Qi-chong's shady things, such as petty theft, female adoption and so on.

An easy-to-understand example is that you compete with a female colleague for the same position, and then she gets promoted by some shady means. This is the so-called hidden block.
