What does the idiom "prepare for war" mean?
Preparing for war should be "preparing for famine", which was put forward in the 1960s in response to the blockade imposed on us by western countries. Its meaning can be literally explained: preparing for war means preparing for battle (all the people are soldiers), and preparing for war means hoarding food and coping with foreign blockades. -in a word, "dig deep, accumulate grain widely, and do not seek hegemony"!
