政贵有恒

国家大政贵在稳定持久。“政”指国家根本性的制度、法令、政策；“贵”即崇尚；“有恒”即保持稳定。一个国家，尤其是大国，一定要保持其根本制度、根本大法的稳定性、持久性，不能朝令夕改，反复无常，否则会引起政局动荡、社会混乱；尤其在根本性问题上不能出现颠覆性变化，否则难以挽回和弥补。这个道理和“治大国若烹小鲜”有相通之处。

Stability Is the Key to Governance

It's the key to governance to ensure sustained stability. Zheng refers to the fundamental systems, laws, and policies of a state. Gui means the most valuable thing. Youheng means to ensure stability. A country, especially a large country, must preserve the constancy of its basic systems and fundamental laws. Laws, especially fundamental ones, must not be changed from time to time at random. Otherwise, the country will land into political turmoil and social chaos, resulting in irreversible and irreparable damages. This is the same notion as embodied in the saying "governing a big country is like cooking small fish."
