The philosophical truth embodied in the sentence "Be prepared for danger in times of peace" is that although "safety" and "danger" are in two opposite situations, under certain conditions, the two can also transform into each other. This That is to say, as mentioned in philosophy, when "quantity" accumulates to a certain extent, it will cause "quality" to change.

The Chinese idiom "Be prepared for danger in times of peace" means to always remain vigilant in a comfortable and peaceful environment. This idiom comes from the "Eleventh Year of Duke Xiang" in the famous ancient Chinese history "Zuo Zhuan". The original sentence in the article is, "I am not happy about the security inside and outside, but I am happy that your Majesty is in peace and is prepared for danger." This sentence was what Wei Zheng said to Emperor Taizong of the Tang Dynasty.

The idiom of being prepared for danger in times of peace also tells us that a comfortable life often causes many people to lose their awareness of danger. When a crisis really comes, they are often unable to cope with it and solve it. Therefore, in our daily life, we should learn to prepare for a rainy day, make plans and plans as early as possible when doing things, and always maintain a clear understanding.
