In the winter of the 15th year of Yongkang in Qi State, it snowed for 13 consecutive days in Yancheng, the capital of the country. Emperor Yongkang, the monarch, was ill for a long time and died the following year.
In the same year, the crown prince of Qi succeeded to the throne in the Ming and Qing Dynasties and changed the name of the country to Yongping. He was only five years old.
In the spring of the second year of Yongping, King Lin of Qi State led his troops to attack Yancheng in the name of "Qing Jun Side" and was defeated.
In the third year of Yongping, Emperor Yongping killed the five kings of Qi - King Lin, King Ping, King Huai, and King Xian, on the pretext of fulfilling "the last wish of the late emperor - the chaos in Pingguo".
People all over the world say, "Thirteen consecutive snows, Yongping conquered Yongkang, the eight-year-old emperor killed five kings, and the world was in trouble."
