Who is Zhou Wenwang in Three-body?

Fuxi wants to hypnotize the sun with a giant pendulum. He thinks the sun is a great god. When he is awake, it is a chaotic era, and when he is asleep, it is a constant era.

Zhou Wenwang used Yin and Yang to explain it. He drew sixty-four hexagrams to calculate the eternal era. Unfortunately, they are both wrong. The sun never rose again, and three flying stars appeared. Zhou Wang cooked Fuxi and Zhou Wenwang with bronze tripod.
