I discovered by chance that reading classical Chinese to my daughter before bedtime can help her sleep, so lately I’ve been using the Zizhi Tongjian as a bedtime story. I read a passage from the original text and casually explain it (skipping over any unclear explanations or parts I don’t understand myself). Sometimes I skip explaining altogether. My daughter chimes in when she finds it interesting, then closes her eyes and rests when she finds it boring. She usually falls asleep soon after.
Sometimes, however, I’d find something so captivating that even children would find it so engaging that they’d forget about sleep. One evening, I found the section about Liu Heng (then Prince of Dai, later Emperor Wen of Han) being recruited to become emperor quite fascinating, especially because it so thoroughly (and quite succinctly, actually) described Liu Heng’s exceptionally cautious character.
The story takes place in 180 BC. After the death of Empress Lü, Liu Bang’s wife, Empress Lü, discontent with the Lü family’s power, the Liu family’s kings, led by the King of Qi, revolted. The ministers, led by Prime Minister Chen Ping and Grand Marshal Zhou Bo, seized the opportunity to launch a palace coup, destroying the Lü family’s power fostered by Empress Lü. At this time, there was a little emperor, Liu Hong (12 years old), in the palace. However, that child was given to her daughter-in-law (also her granddaughter) to raise. The ministers were afraid that he would be detrimental to everyone when he grew up (such as settling scores after the autumn harvest), so they said that he was not the biological son of Emperor Hui of Han (God knows if it was true), and planned to find someone to replace him as emperor to ensure the purity of the Liu family’s bloodline and their own safety. So they discussed -
The ministers conspired together and said, “The Shaodi and the kings of Liang, Huaiyang, and Hengshan are not the true sons of Emperor Xiaohui. Empress Lü schemed to falsely claim the sons of others, killed their mothers and raised them in the harem, then made the sons of Emperor Xiaohui and established them as empresses along with the other kings in order to strengthen the Lü family. Now all the Lü clans have been wiped out, and the eldest has been appointed as the queen and is in charge of affairs. We are no longer of the same kind. It would be better to establish the most virtuous among the kings.” Someone said, “The King of Qi is the eldest grandson of Emperor Gao, and he can be established.” The ministers all said, “The Lü family is evil because of their relatives and almost endangered the ancestral temple and disturbed the meritorious officials. Now the uncle of the King of Qi is Si Jun, who wears a tiger crown. If the King of Qi is established, the Lü family will return to the family. The King of Dai is the eldest son of Emperor Gao, who is kind, filial, and generous. The Queen Mother’s family, Bo, is cautious and good. Besides, establishing the eldest son is in harmony with the people, and he is known throughout the world for his kindness and filial piety!” So they conspired together and secretly sent someone to summon the King of Dai.
The term “conspiracy” isn’t meant to be pejorative; it simply meant a secret discussion, one that the young emperor couldn’t know about. Hence the “secret summons to the King of Dai,” a move that meant secretly sending someone to invite him. The ministers considered the two best candidates: Liu Bang’s eldest grandson, Liu Xiang, the King of Qi, and his oldest son, Liu Heng, the King of Dai. Liu Heng was chosen, not only for his reputation for benevolence and filial piety, but also primarily because his mother, the Bo family, was known for its low-key, environmentally friendly, and pollution-free approach.
Now, let’s move on to the reaction of King Dai, Liu Heng. While there aren’t many words about him, they’re powerful, clearly and concisely outlining his character. The comments in brackets are from someone named A.
When the King of Dai asked his attendants (Liu Heng had no reaction when he heard that the ministers had summoned him to the capital, so he immediately listened to the opinions of those around him), the Imperial Physician Zhang Wu and others said, “The ministers of Han are all former generals of the Emperor Gao, experienced in military affairs, and full of deceit. Their intentions are not limited to this, they are just afraid of the power of the Emperor Gao and the Empress Dowager Lü. Now that the Lü clan has been exterminated and the capital has just been drenched in blood, they are using the name of welcoming the King to see the King, which is really not credible. I hope the King will feign illness and not go, so as to see how the situation develops.” (The Imperial Physician was in charge of guarding the inner court. Judging from this opinion, Zhang Wu tended to be conservative.) Lieutenant Song Changjin said, “The opinions of the ministers are all wrong. When the Qin Dynasty lost its power, the princes and powerful people rose up, and everyone thought they had won the throne, and it was the Liu family who finally ascended to the throne. The world was hopeless, that’s one thing. The Emperor Gao granted titles to his princes and brothers, and the lands were controlled by each other. This is what is called a rock-solid clan, and the world was subdued by its strength, that’s two. When the Han Dynasty rose, it abolished the harsh policies of the Qin Dynasty, made laws and decrees, and bestowed benefits on everyone, so that everyone was at peace. It’s difficult to shake, for the third time. Empress Dowager Lü’s strict rule established the Lü clan as the Three Kings, allowing them to usurp power and dictate the dictatorship. Yet, the Grand Commandant, with a single call to arms, entered the Northern Army, and the soldiers all sided with the Liu clan, rebelled against the Lü clan, and ultimately destroyed them. This was a gift from Heaven, not human effort. Even if the ministers desire change, if the people are unwilling to follow their lead, how can their factions truly unite? Internally, we have close allies with Zhuxu and Dongmu, while externally, we fear the might of Wu, Chu, Huaiyang, Langya, Qi, and Dai. Of Emperor Gao’s sons, only the King of Huainan and the Great King remain. The Great King is also the eldest, renowned throughout the land for his virtue, benevolence, and filial piety. Therefore, the ministers, guided by the will of the people, want to welcome and enthronize the Great King. The Great King should not doubt it. (Lieutenant Song Chang, with scant information, accurately guessed the intentions of the court ministers through logical reasoning. The Lieutenant commanded the garrison at the capital. Song Chang’s words demonstrate his excellent judgment and suggest that he is more suited to overseeing foreign affairs. His advocacy on this matter was very positive.)
Liu Heng received two opinions: Zhang Wu’s and Song Chang’s. Judging from Song Chang’s comments, Zhang Wu’s opinion was likely the majority, as few supported Song Chang’s view at the time. However, Song Chang’s opinion clearly moved Liu Heng, perhaps aligning with his own judgment, and he began to be tempted. Even so, he didn’t take action. He then consulted relevant individuals.
The King of Dai reported this to the Queen Mother. (At the time, Liu Heng was 23, and it was only natural to consult his mother, Lady Bo, regarding such a major matter. Besides, Liu Heng was a renowned filial son.) Undecided, he consulted a divination (even his mother hesitated, suggesting a genetic predisposition). So they consulted a divination. The prediction was “Da Heng.” The divination said, “Da Heng Geng Geng, I will be the Heavenly King, and Xia Qi will be the Light.” The King of Dai replied, “I am already a king, so what king am I?” The divination replied, “The Heavenly King is the Son of Heaven.” (Whether this divination was true or false, a classic example of successful prediction, or simply a simplistic prediction by the fortune teller? Only God knows. However, it is true that the Han people believed it.)
After consulting his mother and receiving a favorable divination, 23-year-old Liu Heng should have taken action. Not yet! He still felt it wasn’t safe enough and continued to test the waters.
So the King of Dai sent the Queen Mother’s brother, Bo Zhao, to meet with Marquis Jiang. (This time, he asked his uncle to go first and ask questions, specifically to Marquis Jiang, Zhou Bo, who had been most instrumental in exterminating the Lü clan. The choice of Zhou Bo over Prime Minister Chen Ping was significant: Zhou Bo was known for his honesty and disliked the roundabout ways of scholars, while Chen Ping was known for his cunning and scheming. To inquire about the situation, one naturally sought the most direct.) Marquis Jiang and the others explained to Zhao their intention to welcome the king. Bo Zhao replied, “It is true, beyond any doubt.” The King of Dai smiled and said to Song Chang, “It is just as you said.”
After sending his uncle to ask Zhou Bo, Liu Heng was basically convinced that Song Chang’s judgment was correct. He decided that it was time to set off, but was it just a simple matter? No, he still needed to make some preparations.
He ordered Song Chang to accompany him on the journey, and Zhang Wu and six others to ride on the carriage to accompany him to Chang’an. (Liu Heng did not bring many people with him, but they were all his most trusted people.)
At Gaoling, they rested, while Liu Heng sent Song Chang ahead to Chang’an to observe the situation. (Gaoling was still dozens of miles from Chang’an, so Liu Heng stopped here to send Song Chang, his most discerning advisor, to scout the route. This way, in case of danger, there would still be a chance for escape.) Chang arrived at Weiqiao, where he was greeted by the prime minister and his subordinates. Chang returned with his report. (Song Chang reported that all the high-ranking officials, from the prime minister down, had arrived; there was clearly no sign of a trap to capture him!) The King of Dai rushed to Weiqiao, where his ministers paid their respects and swore their loyalty. The King of Dai dismounted and bowed in return. Grand Marshal Bo stepped forward and said, “I would like to ask for a briefing.” Song Chang replied, “If you are speaking publicly, I will speak publicly; if you are speaking privately, the king is impartial.” (Zhou Bo’s statement likely meant that he invited the King of Dai to a quiet place to discuss privately, presumably suggesting that he still felt the need to “secretly” present the imperial seal and military talisman. However, Song Chang immediately stopped him, which was actually Liu Heng’s intention.) The Grand Marshal knelt and presented the imperial seal and talisman. The King of Dai thanked him, saying, “We will discuss this matter at the Dai residence.”
Liu Heng’s journey to Chang’an was a dangerous one. If a trap were set, or if someone (like the King of Qi, who knew the news) intercepted him, he might never return. Therefore, he was extremely cautious. But when Zhou Bo knelt and presented the imperial seal, he didn’t happily accept this gift. Instead, he politely said, “Let’s discuss it at the Dai State Guesthouse.” Why? On the one hand, he was indeed very low-key. On the other hand, only the Grand Marshal Zhou Bo and a few ministers presented the imperial seal. What about the more important civil official, the Prime Minister Chen Ping? Liu Heng still felt uneasy.
On the last day of the ninth month of the following year, the King of Dai arrived in Chang’an and took up residence in the Dai Palace, accompanied by his ministers. Prime Minister Chen Ping and others bowed twice and said, “Zi Hong and others are not sons of Emperor Xiaohui and should not serve in the ancestral temple. Your Majesty, as the eldest son of Emperor Gao, should be the heir. May Your Majesty ascend the throne.” The King of Dai gestured westward three times and southward twice, then ascended the throne. The ministers followed the courteous orders.
Arriving at the Dai Kingdom Hotel, which was, in a sense, the Dai King’s personal territory (the equivalent of a consulate), Prime Minister Chen Ping led the civil and military officials in pleading with him to become emperor. He should have agreed, and indeed he did, but he had to offer his seat facing west three times, then twice more for a seat facing north and south, before finally, “reluctantly,” agreeing. How tiring!
Dongmu Marquis Xingju said, “I have no merit in exterminating the Lü clan. I request to be removed from the palace.” He entered the palace with Grand Coachman Ruyin Marquis Tenggong and addressed the young emperor, saying, “You are not a descendant of the Liu clan, so you should not be enthroned!” He then turned and ordered the halberd bearers around him to withdraw their weapons. Several refused to disband, but the eunuchs ordered Zhang Shi to announce their decision, and they too withdrew. Tenggong then summoned the imperial carriage to take the young emperor out. The young emperor asked, “Where do you want to take me?” Tenggong replied, “I will go to my residence.” He then left the palace with the Grand Chamberlain. Then, in the imperial carriage, he welcomed the King of Dai to his residence and announced, “The palace has been removed.”
——This paragraph talks about how Liu Xingju, Marquis of Dongmu, and Xiahou Ying, Duke of Teng, moved out of the palace, that is, they moved the 12-year-old Emperor Shaodi Liu Hong out of the palace to make room for Liu Heng.
That evening, the King of Dai entered the Weiyang Palace. Ten heralds holding spears were guarding the Duanmen Gate, saying, “The Emperor is here. Why are you entering?” The King of Dai then spoke to the Grand Marshal. The Grand Marshal went to explain, and the ten heralds all drew their weapons and left, allowing the King of Dai to enter.
This passage is also quite interesting. After the palace was cleared, Liu Heng and his men attempted to enter the Weiyang Palace, but ten armed guards barred their entry. Logically, having already seized the imperial seal, Liu Heng could have ordered them executed or driven away. However, he politely summoned the Grand Marshal Zhou Bo, who gave the order before allowing Liu Heng into the palace.
That night, Song Chang was appointed General of the Guards to pacify the armies of the north and south; Zhang Wu was appointed Imperial Secretary to march through the palace. Officials dispatched troops to execute the kings of Liang, Huaiyang, and Hengshan, as well as the young emperor, at his residence. Emperor Wen returned to the front hall, and that night, he issued an imperial edict granting amnesty to the entire nation. (From Volume 13 of “Zizhi Tongjian”)
— Earlier, we’ve discussed how Liu Heng hesitantly followed his ministers into Chang’an and the palace to become emperor. However, once inside, he immediately made several decisions: first, he appointed Song Chang as commander-in-chief of the capital’s garrison, commanding both the Southern and Northern armies (when the Lü family was exterminated, Zhou Bo had simply swindled the Northern army’s military power to seize control, demonstrating the importance of this position). He then appointed the relatively conservative yet equally loyal Zhang Wu as commander of the palace guard. Without hesitation, he dispatched various departments to immediately execute the young emperor, Liu Hong, and several other Liu princes suspected of having Lü ties, essentially eradicating the problem at its roots—a strategy likely echoed by the ministers themselves. And that very night, he ascended to the throne as emperor, unable to wait even for the next day! Just look at how thrilling this day was!
From this last paragraph, we can see that Emperor Wen of Han, Liu Heng, was very low-key, humble and respectful on the surface, but his political talent was also extraordinary. He handled things very quickly and neatly. This aspect may have been inherited from his father, Liu Bang.
