郑观应的传世之作《盛世危言》,是近代中国版本最多的名著。由于郑观应曾屡次修订、重印这一著作,当时的社会又无版权观念,书商等人不仅随意翻印书籍,甚至自行改变卷次、增删文章,致使《盛世危言》的版本十分繁杂。 最早问世的《盛世危言》是五卷本。而书名仅有“盛世危言”四字的版本,都是此种五卷本。五卷本的卷首有郑藻如撰写于“壬辰 （1892）八月中秋节”的序言,其中有“阅既竟,乃璧还原本,并劝其早付手民,出以问世”之句,表明在此时《盛世危言》尚未排字。在该版本的卷首还有“先后参定”该书的吴广霈、杨毓恽和陈炽分别撰写于“壬辰仲冬”、“癸巳（1893）暮春之初”的后跋及“癸巳七月”的序言,它们表明,在1893年阴历七月,《盛世危言》五卷本仍未付印。到中日甲午战争于1895年4月结束之后,郑观应于这一年年中或下半年为《盛世危言增订新编》撰写了《凡 Zheng Guan-ying handed down as “heyday”, is the most modern Chinese version of the famous.
