In the second year of Wude, Princess Qin gave birth to her eldest son. According to historical records, because the Prince was born in the Taichi Chenggan Palace, it is a clever word to name this temple Li Chenggan. However, although the word "Chenggan" is a palace name, it is of great significance when used as a person's name. Therefore, the name "Cheng Gan" was given to him by the grandson of Tang Gaozu tang gaozu.
In the third year of Wude, Li Chenggan, who was still in infancy, was named King Hengshan.
In the fifth year of Wude, Li Shimin appointed his wife's nephew and grandson of Changsunchi as Li Chenggan's assistant.
In the seventh year of Wude, Li Chenggan moved to seal Zhongshan King. Pacify the queen, and appoint Lu Deming and Kong, two masters of Confucianism, as eighteen bachelors of Qin Dynasty, to teach Li Chenggan Confucian classics. Therefore, after Li Shimin acceded to the throne, he said that Cheng Gan "had heard of Ruizhe early, and the young people appreciated poetry", which was not to brag.
In the same year, Li Shimin appointed Sun Xiang, the younger brother of Chang Sun Jiaqing, as the hero of Zhongshan Palace in Li Chenggan.
In the ninth year of Wude, Li Shimin became Emperor Taizong. In October, Li Chenggan, who was only 8 years old, was made a prince. According to historical records, Cheng Gan was intelligent by nature, sensitive and considerate, handsome in appearance and pure in benevolence and filial piety. Emperor Taizong liked him very much, and Li Chenggan, as the Crown Prince of the Tang Dynasty, started a life that attracted people's attention under one person.
In the third year of Zhenguan, Prince Li Gang had to take a sedan chair into the palace because of foot disease, so Li Chenggan personally led his teacher to the temple and bowed respectfully, respectfully asking him, with a very respectful attitude. After Li Gang died of illness, Cheng Gan personally erected a monument for the teacher.
In May of the fourth year of Zhenguan, Emperor Taizong issued an imperial edict, saying that "from now on, only those who sue in Shangshu Province will start from the East Palace to make a decision." It can be seen that Emperor Taizong, as Chu Jun, has consciously exercised his political ability, while Li Chenggan was only 12 years old at this time. In the same year, Du Ruhui, the right servant of Shangshu, was seriously ill, and Taizong ordered him to go to express his condolences in person.
In the fifth year of Zhenguan, Li Chenggan was originally scheduled to hold the coronation ceremony in February, but in order not to rob the farming season, Emperor Taizong changed the coronation ceremony to October. In the same year, Li Chenggan was ill, but Emperor Taizong, who never believed in Buddhism or Taoism, invited the Taoist Qin Ying to pray for his beloved son. After Cheng Gan recovered from his illness, Emperor Taizong summoned 3,000 monks to build Xihuaguan and Puguang Temple, which lightened the crimes of prisoners in prison and prayed for his son.
In the sixth year of Zhenguan, Emperor Taizong was lucky enough to be in qi zhou, and Li Chenggan stayed in Beijing as a prince to supervise the country. In August, when Li Chenggan came to Korea, Emperor Taizong was happy, and officials of the East Palace gave a big banquet, giving different silks.
In the seventh year of Zhenguan, Li Chenggan was seriously ill, and Emperor Taizong ordered Buddhist monk Bo of Tianzhu to pray for his son. After Cheng Gan recovered from his illness, Emperor Taizong gave Bobo sixty silks and ten horses in time. At the same time, because Cheng Gan was ill, in order not to let him work too hard, Emperor Taizong specifically allowed him not to read more books, and only commented on the past with Kong. However, Li Chenggan did not take the opportunity to indulge himself. On the contrary, he showed his outstanding talent in governing the country and keeping the country safe. On one occasion, Emperor Taizong asked him to try to write a general plan for governing the country. As a result, he quickly wrote three pages of valuable content. After reading it, Emperor Taizong proudly showed off to the courtiers and said, "First, prison is the most important and won the favor of the country."
However, Emperor Taizong was also worried that Cheng Gan "grew up in the deep palace and the people were ugly", so he said to Yu Zhining and Du, the sons of Prince Zuo, "Qing and others often talk about the interests of the people. ..... Every time I see something wrong, it's better to say it, which will be good. " And Li Chenggan is also very studious. He not only asked Kong Ying Da to write "Chapters of Filial Piety", but also asked Yan Shigu to annotate Ban Gu's "Hanshu" in detail, and then solemnly put it on the table after the manuscript was finished. Emperor Taizong praised this and treasured it in the secret cabinet of the Royal Library, and gave Yan Shigu 200 antiques and a good horse.
In February of the eighth year of Zhenguan, Prince Li Chenggan took Canadian dollars, so Emperor Taizong pardoned his capital crime and gave him more than five sons as fathers, who were knighted. He stayed in the world for three days, held a grand banquet for his ministers and gave silk to different people. In March, Emperor Taizong was lucky enough to be in Jiucheng Palace, and in September, Ding Chou and Li Chenggan came to North Korea. At that time, Li Chenggan asked Zhu Shuode to collect the lecture notes of the Hong Wen Pavilion. He also remembered that "the emperor built a temple for me and called for merit", and specially invited the Taoist monk of Puguang Temple to come, which was very polite.
In the first month of the ninth year of Zhenguan, Li Chenggan married Su Shi, the eldest daughter of Sioux City, a minister, as a crown princess, and Emperor Taizong gave a big banquet and presented silks to each other. In May, Gengzi and Tang Gaozu Li Yuan died of illness. During the mourning period, Emperor Taizong issued a letter to the prince to supervise the state power and understand military affairs, while Li Chenggan was "quite knowledgeable" and "quite able to smell things" and did a good job. In June, the courtiers begged Emperor Taizong to go to court to listen to politics, and Emperor Taizong agreed, but "the details are still entrusted to the prince." Later, Emperor Taizong went on patrol, and the prince stayed in Beijing to supervise the country.
After ten years of Zhenguan, my eldest grandson was seriously ill. Cheng Gan was worried, so he asked for an Amnesty for the prisoners, hoping for blessings, but his eldest grandson flatly refused. So Cheng Gan didn't dare to ask for Amnesty, but told his prince, and the courtiers heard about it and begged for Amnesty. Although the eldest grandson finally refused the amnesty, Emperor Taizong found another way and ordered the repair of 392 abandoned temples to pray for his beloved wife. However, such touching feelings of husband and wife and mother and son failed to recapture the queen from death. At the end of June, the 36-year-old Grandson Queen collapsed in Li Zheng Hall.
In April of the 11th year of Zhenguan, Li Chenggan made a full sutra in Yanxing Temple.
In March of the 12th year of Zhenguan, Li Xiang, the eldest son of Li Chenggan, was born. Because of the joy of the birth of the emperor's grandson, Emperor Taizong ordered all prisoners banned in the world to be punished first, and the internal and external official positions were above five grades. The latter, the change of honor, was celebrated in the East Palace for five days. In the same year, Li Chenggan had a very successful academic exchange among Buddhism, Taoism and Confucianism in Yuhong Wentang. Not only the prince himself "smiled happily", but all the participants "sat together happily".
In the thirteenth year of Zhenguan, Emperor Taizong ordered the establishment of Chongwen Pavilion in the East Palace. Chongwen Pavilion is a learning pavilion specially set up by Emperor Taizong for Prince Li Chenggan during Zhenguan period. Bachelor of Chongwen Pavilion teaches students with classic books from the East Palace, but all lectures are sent to Hong Wen Pavilion.
However, at this time, with the increase of age and the aggravation of foot disease, Li Chenggan began to resist. As a result, Emperor Taizong "searched for sages to help store the palace" and successively selected more than ten old ministers as assistant ministers of the East Palace, such as Yu Zhining, Li Baiyao, Du Fu, Kong, Zhang Fang and Wei Zhi. He ordered Cen Wenben and Ma Zhou to consult with Prince Chenggan in the East Palace. However, these remonstrators have neglected a very important point, that is, whether this educational method is suitable for Li Chenggan, and whether the remonstrance blindly can correct Cheng Gan's deviant behavior? Because we can find common ground through the persuasion of Yu Zhining, Kong, Zhang and others-these three people are almost more sparse than before, and the wording is more intense than one, and the words are more sharp than one, but in the end they can't get the expected effect at all.
In the fourteenth year of Zhenguan, Li Chenggan only built a house, and Yu Zhining criticized him for being too extravagant. Li Chenggan played with eunuchs, but Yu Zhining criticized him and even compared him to Qin Ershi. In contrast, the hole is even more fierce. As long as he thinks there is something wrong with Li Chenggan, he will immediately persuade him face to face. Mrs. Sui 'an, the nurse of the Prince, once advised Kong that the Prince was too old to criticize in front of him, but Kong said that I would "die unsatisfied" and the result was "too much remonstration and too much commitment". As for Zhang, he always remonstrated and his words were urgent, which made Li Chenggan want to listen to him at once. As for the result, it is too clear.
In the fifteenth year of Zhenguan, Li Chenggan led the Turkic clique into the palace privately, which provoked Yu Zhining to write again. Although Li Chenggan was afraid that his father would know before he dared to sneak in, there was no windtight wall in the world, and Emperor Taizong naturally knew what his son was doing. So Emperor Taizong ordered Li Baiyao and others to attend the hall, and told Du that he should always persuade the prince to pay attention to his words and deeds. As a result, Du told Cheng Gan what Tang Taizong said after several times of persuasion failed. Cheng Gan was angry, so Tang Taizong was very dissatisfied with this and asked Du, "Why did you leak my words?" So Du was demoted to the secretariat of Guzhou, and left to the governor of Jiaozhou. Later he was exiled to Zhangzhou for rebellion.
In December of the same year, Emperor Taizong made a fortune in Luoyang, Li Chenggan was in charge of state affairs, and the right servant of Shangshu shot Gao Shilian and Prince Shao Shi. Gengzi and Emperor Taizong also ordered all the eldest sons above the third grade to leave Guandong Palace.
In February of the 16th year of Zhenguan, Emperor Taizong was very happy to complete the manuscript of Boxed Records edited by Wang Wei and Lee Tae. As a result, he not only put the book into the Royal Library, but also sent Lee Tae a series of gifts-first, a "million things", and then a large amount of property every month, even exceeding the specifications of the prince, so Emperor Taizong simply wrote to cancel the restrictions on the use of the library by the prince. Li Chenggan declined politely, and Emperor Taizong replied, "Your family's tomb comes first. The country has two preparations, and you have a destiny to show your difference. ..... I want to protect the road, and I am too lazy to thank you. "
On September 4th, Emperor Taizong appointed Wei Zhi as the prince's teacher. Li Chenggan at this time, for an overly happy person in the palace, has been very lucky. When Emperor Taizong knew it, he naturally put it away. As a result, he was heartbroken, refused to go to court for several months in a row, and even tried to kill Zhang and others who advised him many times. However, even if it became so stupid, Emperor Taizong never thought about abolishing the prince, and even took pains to appoint Wei Zhi as the surname of the prince. The purpose of this move is to tell everyone that he will never fail and inherit this prince.
In the seventeenth year of Zhenguan, Wei Zhi was seriously ill. Emperor Taizong personally took Li Chenggan and Princess Hengshan (renamed Princess Xincheng after Emperor Gaozong ascended the throne) to visit Wei Zhi's mansion. In March, Ang Lee, commander of Zuo Tunwei, said, "Your majesty has failed in dealing with the Crown Prince and other princes. The inheritance of the Prince's country is also willing to think deeply and deeply, so as to secure the feelings of the world. " Emperor Taizong replied, "I know what you mean. Although my son has a kick, he has been an official for a long time. How can he give up his official position and stand upright? "
Emperor Taizong had no idea of easy storage. However, Li Chenggan's younger brother, Lee Tae, is also deeply loved by his father, and has the heart to seek an office and is afraid of it. After trying to assassinate him, he colluded with Han Wang, Xu, Du Wei and Hou of Princess Chengyang, and planned to attack the palace first. As a result, things were exposed. In desperation, Emperor Taizong had to imprison him in another room, and ordered Stuart Wuji, Fang, Tejin Xiao Yu, Ministry of War Shangshu, Dali Fu Jia, Zhongshu Assistant Minister Cen Wenben, suggestion physician Ma Zhou and suggestion physician Chu Suiliang to participate. Everything is clear.
Throughout history, those princes who failed on the road of rebellion often ended in beheading. But when it was Li Chenggan's turn, Emperor Taizong was silent.
Of course, what he did let him down. In order to train Aiko into a qualified Chu Jun, how much effort and energy he has devoted! But Li Chenggan's rebellion was a big mistake, but after all, Emperor Taizong still loved this son and was reluctant to kill him, but he could not openly take the lead in breaking the law. what should he do ？ Finally, Emperor Taizong picked up this thorny issue and threw it to the ministers-what do you think? As a result, no minister dared to answer.
Because there is no need to discuss how to deal with the prince's rebellion, and it should be punished according to law, but now Emperor Taizong openly asks how to deal with Li Chenggan in front of all the ministers, which is obviously saying that he doesn't want to kill Li Chenggan at all. Finally, the general manager came to the rescue station and said, "Your Majesty can be a loving father for life." So Emperor Taizong ordered the abolition of the name of Shu Ren in Li Chenggan and exiled him to Ganzhou, finally saving the life of his beloved son. Lai Ji also got the attention of Emperor Taizong because of this matter, and his official position continued to improve. Soon, he was admitted to Yuan Wailang, and the following year he was promoted to Mr. Sheren in Zhongshu, and co-wrote The Book of Jin with Ling Hudefen and others.
Later, on the occasion of re-establishing the reserve, Emperor Taizong knew that "Lee Tae, Cheng Gan and Wang Jin did not exist; King Jin, Taigong became Gan Kean ",so he decisively appointed Li Zhi, a young but gentle man, as the Prince, in order to keep his three beloved sons, Gan, Li Zhi, at the same time.
In April of the same year,, ordered to commit suicide, and, Hou and others were punished, but the principal offender Li Chenggan was abolished. Emperor Taizong felt in "Abolishing the Crown Prince as a Letter to Shu Ren": "It is better to be buried than to be buried!" However, his beloved son, who had high hopes, finally let him down. Gengyin, Taizong personally went to the ancestral hall and made a mistake with Xie Cheng. In September, Chenggan moved to Ganzhou.
In December of the eighteenth year of Zhenguan, Li Chenggan died in Qianzhou, and Emperor Taizong abolished the dynasty and buried it as a national gift.
Throughout Li Chenggan's life, we can see that although Emperor Taizong was the son of Tiankhan, the emperor of the Tang Dynasty, he still spent a lot of effort and energy in facing his beloved son, just like the 10,000 most ordinary fathers in Qian Qian.
So when Cheng Gan was less than 6 years old, Emperor Taizong invited the famous Confucian master Lu Deming to teach him. So when Cheng Gan 12 years old, Emperor Taizong began to consciously cultivate his ability to handle government affairs. Therefore, after Cheng Gan became older and older, Emperor Taizong took pains to lead him back to the right path. Even when he heard someone guess that the dry storage was unstable, he immediately appointed Wei Zhi as the surname of Prince, which disappointed people. Therefore, even if Cheng Gan later committed heinous crimes such as rebellion, Emperor Taizong still racked his brains to save his life when he was sad, and even when he replaced the crown prince, he was full of plans for the future safety of Cheng Gan.
However, Cheng Gan, who lost the position of Prince, died of depression soon. It's hard for us to know today how sad Emperor Taizong was about the death of his beloved son, but it is said that in the year after Cheng Gan's death, Emperor Taizong wrote a poem "Autumn is the Eye":
Qiu Guang lotus uterus Danque.
Clothes are worn out and shadows are sparse, and flowers are bright and chrysanthemum clusters.
The robe is light and low grass dew, and the side dance is loose.
Flying clouds scatter leaves and get lost.
Build by laying bricks or stones cold orchid withered, boudoir cold tree meteorite tung.
Don't be a crane in a harp, stay away from the crying ape gorge.
Flying stars and wild arrows, empty strings and half-moon bows.
The evening mist of wheat straw rose and the twilight filled the room.
Whether it is the loneliness of seeing autumn chrysanthemums dotted with flowers, or the sadness symbolized by parting cranes and apes, it implies that Emperor Taizong deeply misses his beloved son. It's just that Chenggan has passed away, and Prince Datang, who once attracted much attention, will never come back.
In the twenty-seventh year of Kaiyuan, Li Chenggan's grandson Li became the left image of Emperor Xuanzong of the Tang Dynasty. Li Yin's grandfather's rebellion was abolished, and his father Li Xiang was demoted by Wuhou, so he asked to be buried in Zhaoling. Emperor Xuanzong of the Tang Dynasty posthumously awarded Li Chenggan as the king of Hengshan and the viceroy of Jingzhou, saying that he was buried with Zhaoling. Li Xiang, the father of Li, was posthumously awarded as the secretariat of Yuezhou and lord protector, while his uncle and brother were also "praised" and "praised books and articles, according to the city, sighing in the street".
Decades later, Li Chenggan finally returned to his parents' side. From then on, he was buried in Zhaoling and stayed with his parents forever.
