Pingzhun
Pingzhun ( Chinese 平 準 , Pinyin píngzhǔn - “regulate-balance”) was “an old procedure on the part of the government to buy grain to prevent inflation in times of need”. Officials were established for this purpose as early as the Han Dynasty ( 平 準 官 , píngzhǔn guān ), but similar offices existed as early as the Warring States' times . Its main task was to stabilize the official prices:
„大 农 之 诸官 , 尽 笼 天下 之 货物 , 贵 即 卖 之 , 贱 则 买 之。 如此 , 富商 大 大 贾 无所 牟大利 , 则 反本 反本 , 而 万物 不得 腾 踊 , 故 抑 天下 物 , 名曰平 準。 (...) "
