Song Huan has the heart to sympathize with the people, so to be able to be the monarch, the induction of heaven and man is a very delicate thing. Emperor Wu of the Han Dynasty cancelled an expedition to Luntai (Wheelai, an ancient place name, southeast of present-day Luntai, Xinjiang. In his later years, Emperor Wu of Han realized the mistake of his exhaustive military and decided to stop the war. In the fourth year of the conquest, that is, in 89 BC, the ministers wrote to request that troops be sent to Luntai Tuntian to establish a western region, and Emperor Wu of han issued a "strike against Luntai Tuntian Edict" to review the mistakes to the whole country, stop the expedition, and implement the policy of resting the troops, boycotting, and rejuvenating the peasants). alas! How can those who are sympathetic to the people and are suitable to be kings, who regard the lives of the people as weeds, tolerate them standing on the heads of the people for even a day?
