Story:
During the Warring States period, Deng Xi, a grand master of the State of Zheng, was eloquent and skilled in debate.
He gathered crowds to lecture, advocated for rule of law, helped common people with lawsuits, and openly challenged the traditional rule of rites. His views and proposals were all well-reasoned.
He established the new penal code "Bamboo Penalties," advocating for criminal law reform and the implementation of rule of law, which met with strong opposition from the ruling nobles of Zheng.
