Okay kiddo, have you ever seen a black and white circle? It's called a yin-yang symbol. Yin-yang means balance, like when you have two things that are opposite but they work together perfectly.
The yin part is the black side, and it represents things like the moon, darkness, and quietness. It's kind of like when you're quietly sneaking up on your friend to surprise them!
The yang part is the white side, and it represents things like the sun, brightness, and activity. It's like when you're outside running around and playing with your friends on a sunny day!
Together, yin and yang balance each other out, like two sides of a see-saw. This means that even when things seem really different, they can still work together to make things just right.
For example, if you want to make a yummy cake, you need sweet ingredients like sugar (yang), but you also need things like flour (yin) to balance it out.
So remember, yin-yang means balance and working together perfectly, even if things seem very different.
