防民之口,甚于防川 is a Chinese idiom (chengyu) meaning “Suppressing public opinion or criticism leads to greater harm than blocking a river, implying that it is dangerous and ultimately ineffective to prevent people from expressing their views”. Literally, “Stopping people's mouths is worse than blocking a river”.
During the Western Zhou Dynasty, King Li of Zhou was notoriously tyrannical. Shao Gong advised King Li not to be too extreme, but King Li responded by sending agents to monitor the people's words and actions on the streets.
As a result, people dared only to exchange glances when they met, afraid to speak.
Shao Gong sighed, stating that 'stopping people's mouths is more dangerous than blocking a river,' emphasizing that such an approach was excessive and unsustainable.
Before long, the enraged populace rose up and overthrew King Li.
