陈陈相因 Chen Chen Xiang Yin
Explanation
陈陈相因，指沿袭老一套，没有创新。它源于《史记·平准书》中对汉初国库粮仓充盈的描述，后被引申为贬义词，形容墨守成规、缺乏进取心。
Chen Chen Xiang Yin refers to blindly following the old ways and lacking innovation. It originates from the "Records of the Grand Historian", describing the abundance of grain in the Han Dynasty. It's later used as a derogatory term, characterizing inflexibility and lack of initiative.
Origin Story
西汉初年，刘邦励精图治，采取休养生息的政策，国力得到显著恢复。百姓安居乐业，农业生产快速发展，粮食丰收。国库充盈，粮仓堆满了粮食，甚至堆放在露天，日积月累，陈粮与新粮相叠，有的粮食甚至腐烂变质。后世以此典故，比喻沿袭老一套，缺乏创新和改革精神。汉文帝、景帝时期，虽然统治者励精图治，但延续了休养生息的政策，也导致了“陈陈相因”的局面。粮食堆积如山，仓库爆满，甚至露天堆放，许多粮食腐烂变质，白白浪费。这并非因为统治者无能，而是因为当时国家生产力水平的限制，导致了粮食过剩和储存难题。
In the early Western Han Dynasty, Emperor Gaozu worked diligently to govern and implemented a policy of recuperation and peace, leading to a significant recovery of national strength. People lived in peace and contentment, agricultural production developed rapidly, and harvests were abundant. The national treasury was overflowing, granaries were piled high with grain, even stored outdoors. Over time, old and new grains stacked up, and some grain even rotted and spoiled. Later generations used this anecdote to illustrate the continuation of old methods and lack of innovation. During the reigns of Emperors Wen and Jing, although the rulers worked diligently, the continuation of the recuperation and peace policy also resulted in the "Chen Chen Xiang Yin" situation. Grain piled up like mountains, warehouses were overflowing, even stored outdoors, and much of the grain rotted and went to waste. This was not due to the incompetence of the rulers, but to the limitations of the productive forces of the time, which led to grain surpluses and storage problems.
