"Be prepared for danger when you are in peace, and be prepared when you are prepared." It comes from "Zuo Zhuan·Xiangong Eleventh Year" written by Zuo Qiuming during the Spring and Autumn Period. It means that when you are in a safe environment, you should take into account possible dangers and consider You will be prepared when you encounter danger. If you are prepared in advance, you can avoid disaster.

During the Spring and Autumn Period, twelve kingdoms including Song, Qi, Jin, and Wei jointly sent troops to attack the State of Zheng. The king of Zheng hurriedly sued for peace from Jin, the largest of the twelve kingdoms. After Jin agreed, the other eleven kingdoms stopped attacking. In order to express his gratitude, the king of Zheng sent a large number of gifts to Jin.

The king of Jin, Duke Jin, was very happy when he saw so many gifts. He gave the eight singing girls to his hero Wei Jiang and said, "You have given me advice in the past few years, and everything has been done well." Everything went smoothly, and we were in harmony like playing music. It's great. Now let's enjoy it together." Wei Jiang declined the gift and advised Jin Yugong: "Let's enjoy it together! The success of the country's affairs must first be attributed to your talents, and secondly to the concerted efforts of your colleagues. What contribution can I personally make? I only hope that while you are enjoying yourself, you can think of the many things that the country still needs to do. There is a saying in "Shu Jing": "Be prepared for danger when you are in peace. If you are prepared, you will be safe." I would like to advise my lord with these words! Duke Ao of Jin was very moved after hearing this, and happily accepted Wei Jiang's opinion, and respected him even more from then on.
