I've been hearing about the Yin-Yang theory in Chinese medicine. Can you explain it to me?

The Yin-Yang theory is a philosophical and metaphysical concept that describes the interdependence of two opposite but complementary forces or principles. It is based on the idea that everything in the universe has its own unique characteristics, yet is also interconnected with other things. This includes the physical world, as well as the spiritual and psychological dimensions.
