Since ancient times, no matter what the reason, the people who have seized the throne have been called traitors and thieves, and have been scolded by the ages, but Liu Yu is a special case. During his reign, his nephew Liu Ziye was absurd, forcibly occupying his aunt and sister, and even making his uncle Liu Yu the "King of Pigs".
Liu Yu endured humiliation and burdens, secretly gathered righteous soldiers, and killed his nephew to seize the throne as soon as he gained power. The courtiers originally wanted to finally get rid of the absurd monarch, but they did not expect that although Liu Yu had proclaimed himself emperor of Song Ming, he would emulate Liu Ziye in watching the naked female performance.

When Liu Yu was fifteen years old, his birth mother had already died, and Empress Lu pitied him for his loneliness, so she personally raised him, at this time Liu Yu's brother Emperor Xiaowu of Song had already succeeded to the throne, although Emperor Xiaowu of Song was suspicious, he was extremely filial, because of Empress Dowager Lu, Emperor Xiaowu of Song loved Liu Yu and Wu, mostly for care, although he killed his brother because of his suspicions, he always left enough face for Liu Yu.
After the death of Emperor Xiaowu of Song, Liu Ziye, as the eldest son, succeeded to the throne, and Liu Ziye was not loved by Emperor Xiaowu of Song when he was young, and the royal family members thought that he could not ascend the throne smoothly, so they often humiliated him. As soon as Liu Ziye gained power, he began to take revenge on these royal relatives, humiliating and slaughtering them.
The Book of Song records: "When the deposed emperor was rebellious and rebellious, he cursed the people, feared his fathers, and imprisoned in the temple, beating and beating ling, and there was no reason for him to recover." Xiu Ren and Taizong and Xiu You, the King of Shanyang, were fat and strong, and the emperor was called the King of Pigs after the bamboo cage trumpet."

Although Liu Yu lost his mother at an early age, he had always lived in the favor of the empress dowager and the favor of Emperor Xiaowu of Song, and now that he was so humiliated by his nephew, he naturally had every reluctance in his heart, but he knew that Liu Ziye was cruel and cruel, and as far as the current situation was concerned, his life was like something in his hand, if he wanted to live, he had to endure this strange shame.
Liu Ziye, the deposed emperor of the Song Dynasty, in order to let his uncle Liu Yu sit in the name of the pig king, "taste the rice in the wooden trough, the omnivorous food inside, stir up the order and he, dig the ground into a pit trap, and really use muddy water, naked Taizong's inner pit, and the trough food in front, so that Emperor Taizong will eat in the trough with his mouth, and use it for laughter." ”
What does that mean? This means that in order to make Liu Yu worthy of the title of "Pig King", Liu Ziye used a wooden trough to serve rice, and then put in all kinds of omnivorous food, mixed and mixed, and then dug a pit on the ground, filled it with muddy water, stripped Liu Yu of his clothes, put it in the pit, put the wooden trough containing omnivorous food in front of him, and ordered him to eat in the trough with his mouth like an animal, so as to laugh and have fun.
But even so, Liu Ziye still could not eliminate the jealousy in his heart for Liu Yu and others, he even had the idea of killing people many times, but they were all resolved by Liu Xiuren with playful words, and during this period of enslavement, Liu Yu's mentality gradually became more and more mature but gradually distorted. He knew that his nephew Liu Ziye was cruel and cruel, and if he did not strike first, he would be killed in the future.
So he bribed Liu Ziye's close confidant Shou Shuzhi in advance, and on January 1, 466, that is, on the evening of November 30 of the first year of Jinghe, he tricked Liu Ziye into saying that there was a ghost in the Bamboo Hall of Hualin Garden, and asked him to personally shoot the ghost in the Bamboo Hall of Hualin Garden. As soon as Liu Ziye entered, he was killed by Shou Lonely, when he was seventeen years old!
He then accepted the support of his accomplice Liu Xiuren and ascended the throne as emperor for Emperor Ming of Song, changing his name to Yuan Taishi. At the same time, Liu Ziye's brothers and sisters Liu Zishang and Liu Chuyu were executed, and they controlled the military power inside and outside the Beijing Division.
When Liu Yu first ascended the throne, he diligently repaired internal affairs, developed the military, and successively pacified Huainan and other places in the south of the Jiangsu Province, and the Southern Song Dynasty presented a thriving scene. However, not long after, Liu Yu emulated his brother Liu Jun, the Emperor Xiaowu of Song, and wantonly killed the royal family relatives, and even followed Liu Ziye's example in doing absurd things.
According to the record, the palace banquet, the and the view, the palace banquet was originally a banquet to show the strength of the country to consolidate relations, but in Liu Yu's eyes, the palace banquet was just a place to play. The ministers of the Liu Song court had long been "familiar with the way" of the monarch's fornication, and now that Liu Yu was in a position of great power, no one dared to persuade him, only the empress did not want to see Liu Yu so depraved, so she spoke out to persuade him, and did not expect to be disgusted by Liu Yu, the emperor of the Song Dynasty.
In his later years, although Liu Yu knew that the prince was incompetent, he still had no heart to let the sages, and he killed the imperial family and plotted everything for the prince, but it always became a void.
Although Liu Yu endured humiliation and burdens and seized Liu Ziye's throne, although it became a strange talk for thousands of years, his absurdity in his later years "earned" him a reputation for thousands of years. It can be seen from this that it is not the Savior who can bear the great shame or the Lord of destruction.
Sima Qian commented on the Southern Song Dynasty: "Fu Yi's arrogance of filial piety and emperor Ming's suspicion and forbearance, the protection of the chieftain to be under Yu Mu, fortunately, what is the aftermath? At first, Liu Yu proclaimed himself Emperor Ming of Song, just to wake himself up and warn himself not to follow the old path of his brother and nephew, but gradually, he also forgot his original intention, and the absurdity of the three generations of emperors announced the demise of Liu Songchaotang.
