历代帝王，无不思位传万代；无不思国家长治久安；无不知民犹水也，水可载舟，亦可覆舟之理。但是历史上何以治世少，乱世多?君主帝王像走马灯般换来换去。万世之思，久安之想，不过是帝王头脑中的梦幻泡影。然而魏征却要通过自己的奏疏，把历史上这个老生常谈的老大难话题， The emperors of all ages were all thought to pass on from generation to generation; they were all aware of the long-term stability of the country; no one knew that the people were still water, the water could carry a boat, and the boat could be overthrown. However, in history, how to deal with the world is less, more troubled times? The emperor of the monarchy is like a lantern. The thoughts of all ages, the thoughts of peace, are just dreams in the minds of the emperors. However, Wei Zheng has to pass through his own tricks and talk about this old cliché topic in history.
