Zhang Ju is like an iron bell ringing in the depth of winter. His reforms were the sound of friction between iron and bronze - the "Examination Law" made the bureaucratic skeleton creak, and the "One Whip Law" made the old system tremble. He lived his life as a water conservancy project that became both a dam and a gate. Between intercepting the torrent of corruption and opening the gate to release new water, his flesh and blood gradually collapsed. In the end, the system that he had awakened and maintained with his own hands, which had supported the spine of the empire, was completely crushed.
