The Huns were sent away here, and the domestic political situation was not calm.

In the spring of 165 BC, a yellow dragon appeared in Chengji County (Qin'an County, Gansu). Because of this incident, Prime Minister Zhang Cang was forced to resign.

It's a long story. A year ago, the warlock Gongsun Chen wrote to the imperial court to report on his research results. Gongsun Chen said: According to the doctrine of the end of the five virtues, the Qin Dynasty was a water virtue, Tuke water, and the Han Dynasty replaced the Qin Dynasty, so the Han Dynasty was a soil virtue. Tude will correspondingly have a yellow dragon appear. A new calendar should be promulgated, and the color of the clothes should be changed, and the color should still be yellow.

Prime Minister Zhang Cang is an expert in the legal calendar, and he scoffed at Gongsun Chen's letter and ignored it, "The Han Dynasty is full of water virtue, how can it be Tude!" Changing the color of the costume is even more nonsense, when it is the same as the pre-Qin, the color of the costume is still black. ”

Zhang Cang was quickly slapped in the face. A few months later, a yellow dragon appeared in Chengji County. When Liu Heng heard about it, he called Gongsun Chen as a doctor.

This is a red flag. In addition, Zhang Cang once promoted a mid-term official, who abused his power for personal gain in office and was reported. Above the court, Liu Heng blamed Zhang Cang for negligence in employing people.

Zhang Cang was very ashamed, and when he got home from work, he thought about it: I have been a prime minister for ten years, and it is time to abdicate and make way for Xian. Before completely losing His Majesty's trust, take the initiative to resign, at least look better.

Soon, Zhang Cang applied for retirement on the grounds of old age and illness, which was approved by Liu Heng. Zhang Cang spent his old age as a Beiping waiter, Niu was that he lived for more than a hundred years, and he was still there when Liu Heng died, and it took another five years before he died.

Empress Dou's younger brother Dou Guangguo is talented and has a good character. Liu Heng considered letting Dou Guangguo succeed him as prime minister, but after thinking about it, he gave up, and he expressed his hidden worries to Queen Dou, "I'm worried that the ministers have opinions and think that I am the brother who prefers the queen." ”

Liu Heng finally selected Shen Tujia, the imperial historian, as the next prime minister. Shen Tujia is old enough, he followed Liu Bang to fight, and because of his military merits, he became a captain, and he was the founder of the country. It has been thirty-seven years since the founding of the Han Dynasty, the characters have withered, and there are fewer and fewer founding heroes, who are as precious as the giant pandas. Shen Tujia became prime minister, and the ministers were convinced.

Liu Heng asked Gongsun Chen to clarify the various clothing colors, and ordered another warlock, Aragaki Ping, to set up the Five Emperors Temple. In April of this year, Liu Heng came to Yongdi (Fengxiang County, Shaanxi) with a pious heart to worship the five emperors of ancient times and give amnesty to the world. In April of the following year, he went to the north bank of Weishui to worship the five emperors.

It happened that Liu Ze, the king of Qi, died of illness, Liu Ze had no son, Liu Heng divided the Qi country into six, the fourth son of the eldest brother Liu Fei, Liu Ze's uncle Liu Jianglu was the king of Qi, and Liu Fei's five youngest sons were kings, one person led a county, Liu Zhi was the king of Jibei, Liu Piguang was the king of Jinan, Liu Xian was the king of Jiangchuan, Liu Wei was the king of Jiaoxi, and Liu Xiongqu was the king of Jiaodong.

The powerful state of Qi was divided into six small states, and the threat to the imperial court was greatly reduced.

One day in September 164 BC, the warlock Aragaki Taira begged to see Liu Heng. Entering the temple and saluting, he mysteriously presented a jade cup.

Liu Heng took the jade cup, rubbed it carefully, the jade cup has a round mouth and a straight belly, the color is green, the tentacles are warm, and the bottom of the cup is clearly visible with four seal characters: the owner prolongs life.

Aragaki flattened and said: "The minister watches the sky at night, and there is a colorful aura in the northeast of Chang'an, which rushes straight to the sky. The minister ordered people to look for it and get this jade cup on the north bank of Weishui. This is a rare auspicious sign! ”

Liu Hengda said happily: "Is this really the case? ”

Aragaki swore and said, "How dare the minister lie!" The man who found the jade cup was waiting to receive the reward outside the palace. ”

Doctor Deng Tong joked on the side: "This is a blessing from God to Your Majesty!" ”

Liu Heng was overjoyed and said with a smile: "Okay, good!" Aragaki Ping, you have made another contribution. ”

The next day, Liu Heng ordered someone to pass the jade cup to the ministers to watch. Although Tingwei Zhang Shizhi was puzzled, seeing that the emperor was on the rise, it was inconvenient to pour cold water. The ministers all said that it was the emperor's virtue that moved the heavens.

Liu Heng became more and more happy, and announced: "Just let Aragaki Ping be a doctor." ”

After a pause, Liu Heng discussed again: "Next year is the seventeenth year of my succession, and since there is auspiciousness from the sky, I want to change the yuan and take next year as the first year." ”

Prime Minister Shen Tujia nodded and said, "Very good." In this way, it can show that Your Majesty's blessings are long, and the fortune of the Han Dynasty is prosperous! ”

The ministers seconded the proposal. The matter of changing the yuan has been decided.

Aragaki was triumphant, unaware that a large net was being cast at him.
