Zou Yan

Zou Yan was a Chinese thinker who lived around 300 BC. He was a very important part of the Chinese philosophy known as the Hundred Schools of Thought. Zou Yan believed the universe was made up of two opposing forces called yin and yang. According to Zou Yan, everything in the universe is part of this balance between yin and yang, and when something is out of balance it can cause problems. He thought it was important for people to be in tune with this balance in order to lead fulfilled lives.
