Who put forward the rule of law?

Speaking of Guan Zhong, his titles are really numerous and loud. He was a politician, philosopher, economist and strategist in the Spring and Autumn Period, and also a representative figure of legalists in that era. He assisted and made bold reforms, which made Qi "king and dominate the world" and was known as "the first phase of China". His fame has been shocking from ancient times to the present, and it shines forever. Even this year's college entrance examination essay mentioned him. But his other title is often overlooked, that is, he was the first person who put forward the concept of "ruling the country according to law" in ancient China.
