Worrying and taking care of state affairs can make the country prosperous, while pursuing ease and enjoyment can lead to one's own destruction.

Li Cunxu, Emperor Zhuangzong of the Later Tang Dynasty during the Five Dynasties, worked hard at the beginning and defeated all his opponents to proclaim himself emperor. But later he indulged in music and opera, doted on actors, and did not want to make progress. His subordinates caused rebellion, and actors launched revolts. He died in a military rebellion after three years in office. When Ouyang Xiu wrote "The Biography of Lingguan", he was inspired by this period of history and elaborated on the principle that "worry and labor can rejuvenate a country, and leisure and leisure can destroy one's life." Chinese culture has a strong sense of urgency, especially when the country is in turmoil and the people are in dire straits. Confucius said, "If a person does not have long-term worries, he must have immediate worries." Mencius said, "Be born in worries and die in peace and happiness." They emphasized the importance of maintaining a sense of worry from the perspectives of individuals and the country respectively. Even during the heyday of the Tang Dynasty, Wei Zheng advised the emperor to "be prepared for danger in times of peace, abstain from extravagance and be frugal" in order to achieve long-term peace and stability.

Being prepared for danger in times of peace means that if there is no awareness of danger, it may once again lead to the tragic national destiny during World War II.
