“朝令夕改”已经是古词儿了,而“朝令夕改”的社会现象所产生的心理反应,却形成了一种传统定势。只要社会有令而出,这种心理反应就非常灵敏。不同社会有不同的令(政令法规),就其社会效果看,大体有三种。第一种是有利于社会稳定和历史发展的令,出令者希望付诸实施,令行禁止,长期稳定,因 “Dynamic change” is already an ancient word, and the psychological reaction to the social phenomenon of “Dynastic change” has formed a traditional trend.

The exporter wishes to put it into practice, order it to be banned, and maintain long-term stability.
