Yao Chong, Song Jing's Kaiyuan reign
When Li Longji created the Kaiyuan prosperous era, there were three people who contributed the most: Yao Chong, Song Jing, and Zhang Said. Yao Chong, the first ruler to ascend to the throne after the coup d'état, and the only meritorious man who was not purged by Li Longji, was due to his loyalty and ability, and Yao Chong's retention was to allow him to sweep away the chaos of the government since the end of Li Zhi and revive the legacy of Zhenguan. Song Jing, who is highly principled but less enterprising, as his successor, can make up for the bad shortcomings left by Yao Chong's radical reforms, while Zhang said he needs to sing the praises of Kaiyuan Shengshi.
The reason why Yao Chong and Song Jing were able to rectify the rule of officials unchecked in the early kaiyuan period was inseparable from Li Longji's adjustment of the system of prime ministers, who changed the collegial system of seven to ten prime ministers since Li Shimin's period into a special system of one prime minister and one pair, and the chief prime minister had very great power, and As deputies, Lu Huaishen, Yuan Qianyao, and Su Yong all unconditionally supported Yao Chong's and Song Jing's decision-making, and never ripped each other up on anything, thus perfectly realizing the implementation of the system.
However, after Song Jing left the dynasty, Zhang Jiazhen, who took over, encountered a different situation, and Zhang Jiazhen, who had been demoted from Chang'an, returned and became the third chancellor after Yuan Qianyao, and Zhang Jiazhen used Zhang Jiazhen's younger brother Jinwu's general Zhang Jiayou to successfully overthrow the chief chancellor and climb to Zhang Jiazhen's position.
With the monopoly of power, Zhang said that he began his administrative policy, disarmed 200,000 people, changed the military system to a conscription system, and other measures pushed Li Longji's rule to a higher peak, but he ignored the persuasion of Yuan Qianyao and other deputies, and blindly obeyed Li Longji's behavior of Taishan Fengchan, which also completely turned the harmonious system of the prime minister since the beginning of the new century to the opposite side.

Kaiyuan prosperous
Li Linfu went straight up
The thirteenth year of the kaiyuan dynasty of Taishan Fengchan was the watershed of Li Longji's dynasty, before the sealing of Zen, Li Longji worked hard to govern, forge ahead, and accepted advice like a stream, and Li Tangguo was rich and strong. After sealing Zen, Li Longji was very happy, vigorous construction, and extravagant waste, and Li Tangguo was rich and weak.
Along with Li Longji, the chief chancellor Zhang said that the title of Sheng Shixianxiang made him more and more arrogant, and his opponents often insulted him arbitrarily, monopolizing the right to appoint officials, not only disagreeing with his deputy Yuan Qianyao, but also hating him to the bone, and Zhang's arbitrary and arbitrary behavior was not in line with Li Longji's balancing strategy, whether it was Yao Chong or Song Jing, the position of prime minister did not exceed four years, just to prevent Xiang's power from being too large.
Abandoned by Li Longji, Zhang Shu soon encountered an attack from his opponents, and Yuwen Rong, Cui Yinfu, and the newly rising Li Linfu jointly attacked Zhang Shuo, who had already behaved inappropriately and abused his power, and Zhang Shu was reduced from the chief prime minister to a prisoner of the order, which was unbearable to see.
At the same time as Zhang Shuo's imprisonment, there was also a harem dispute, and Li Longji abandoned his wife Empress Wang, who was suffering with him, and favored Concubine Wu.
Concubine Wu defeated Empress Wang
Princess Wu Huifei had three sons and a daughter, the first two sons died prematurely due to illness, but the third son Li Mao, who grew up in Li Xian's mansion, grew up, and Empress Wang died of depression, and Wu Huifei hooked up with the foreign minister Li Linfu in an attempt to take the position of crown prince.
Li Linfu hitched a ride on Wu Huifei's express train, and Qingyun went straight up, but he was still far from the position of prime minister in his dream. Most of the prime ministers who succeeded Zhang Shu followed in his footsteps, did not think about how to deal with state affairs, and fought with their subordinates every day, whether it was Yu Wenrong or Cui Yinfu, they were constantly consuming Li Longji's patience until Li Longji drove them all out of the court.
Only Li Linfu was not suppressed, he had climbed Li Longji's favorite eunuch Gao Lishi, and after Gao Lishi's secret matchmaking, Li Linfu eventually became a guest of the next prime minister, Han Xiu.
Han Xiu is a figure like Song Jing, who likes to speak bluntly and advise, but Li Longji is no longer Li Longji in the Song Jing period, he hates the minister Bo's face very much, Han Xiu was not long in the position of prime minister, he was bombed down by Li Longji, And before Han Xiu left, he solemnly recommended Li Linfu to Li Longji.
Li Linfu showed his prominence
Li Linfu overthrew Zhang Jiuling
Li Linfu finally became the prime minister, but in front of him there were two highly respected superiors, the chief prime minister Zhang Jiuling and the deputy Pei Yaoqing, Zhang Jiuling was the only duo of prime ministers who could achieve close and seamless cooperation after Song Jing, and solved the serious shortcomings of the official governance in the late Kaiyuan period.
But behind them, there is also a Li Linfu who wants to climb to the highest position, unlike Zhang Jiuling, Li Linfu is an extreme realist, in order to achieve the goal, he will not hesitate to sacrifice anyone and things, let alone the national interests.
Li Linfu was a very clever person, he knew how to cater to Li Longji's thoughts, and never attacked Zhang Jiuling head-on, but whenever Li Longji and Zhang Jiuling, who were good at great achievements, had disagreements, Li Linfu always quietly met with Li Longji and put in front of him a plan that could not only attack Zhang Jiuling but also satisfy Li Longji. This is an indispensable process for the transformation from Ming Jun to Ming Jun.
It was not until Shuofang Jiedu made Niu Xianke appointed Shangshu that the conflict between Zhang Jiuling and Li Longji broke out completely, Zhang Jiuling believed that Li Longji had placed incompetent villains on a high position and seriously affected the reputation of the imperial court, and Li Longji believed that Zhang Jiuling was arbitrary and interfered with his right to appoint officials.
Li Linfu appeared in the position where he should appear at the right time, and once again cleverly catered to Li Longji's ideas, and Li Longji finally decided to drive out Zhang Jiuling, who always let him not come to power, and appoint Li Linfu as the chief prime minister.
Li Linfu defeated Zhang Jiuling
Li Longji killed his third son
Although Li Linfu was able to ascend to a high position, it was certainly related to his scheming and power change, but more importantly, what Li Longji, who was absurd in political affairs and extravagant and wasteful, needed ministers like Song Jing and Zhang Jiuling, and Emperor Xia needed li Linfu's kind of courtiers.
In order to completely monopolize the position of prime minister, Li Linfu began to suppress those up-and-coming heroes. Li Longji's appointment of prime ministers was often promoted by leaps and bounds, and those civilian ministers who had made outstanding contributions to the border were transferred back to Chang'an to fill the vacancies of prime ministers, which Li Linfu absolutely could not accept, and he thought of a good way to appoint Hu Ren as a general.
Li Longji walked towards fainting
Most of Li Tang's Jiangshan were Hu people on the defensive, but these generals who could recruit good warriors never really held the military power, and on their heads, there was always a Wenchen holding the sword of Shangfang in the restraint, Li Linfu changed this phenomenon, he was afraid that Wenchen's merits were too great, he snatched the position of prime minister, transferred Wenchen to all parts of the country, let hu people act as military generals, and it was at this time that An Lushan, which was in turmoil, began to rise.
Zhang Jiuling stepped down, Li Linfu's position was stable, he could finally fulfill his original promise to Wu Huifei, taking advantage of the change of position, Li Linfu increased his attack on the crown prince Li Ying, fabricating their dissatisfied remarks, Zhang Jiuling was still able to guarantee Li Ying's position as prince, after Zhang Jiuling left, Li Ying became the meat on Li Linfu's case board.
Li Linfu and Concubine Wu Huifei put a hat of rebellion on the bodies of the crown prince Li Ying, the Prince of Guang, Li Ju, and Li Yao, the King of Jaws, and Li Longji, who was furious, did not even consider the censorship, and killed three sons in one day.
The culprit, Wu Huifei Wanwan, did not expect that the benevolent Li Longji would actually kill Li Ying and others so much, and she was terrified in her heart, and it was not long before she died of illness in remorse.
Li Mao, who originally had the best chance of inheriting the unification, completely cut off the road to the throne with the death of his mother Wu Huifei, and Wu Huifei's departure not only caused Li Mao to lose the position of crown prince, but also made Li Longji, who had no feelings, finally decide to rob Li Mao's wife Yang Yuhuan as a favorite concubine.
Li Mao was taken away from his wife by his father Li Longji
Li Linfu lost to Yang Guozhong
Li Linfu, who was bent on supporting Li Mao, inevitably fell into a struggle with the new crown prince Li Heng, who had been in control of the court for many years and was full of claws and teeth, was an insurmountable mountain in front of Li Heng. Although Li Heng had the support of Li Chengqian's grandson, the chancellor Li Shizhi, the punishment department Shangshu Weijian, and the heavily armed Emperor Fuwei, he fell into Li Linfu's trap.
The more Li Heng got closer to the chancellor, Shangshu, and general, the greater the possibility of Li Linfu's success, and finally under Li Linfu's secret warning, Wei Jian and Emperor Fuwei were killed, Li Shizhi committed suicide, and the prince Li Heng's wings were all cut off, and he might even face the end of being deposed.
From this point of view, Li Heng's indifference to Li Longji after succeeding to the throne is still forgivable.
Crown Prince Li Heng was suppressed
Li Heng's power in the dprk was overthrown, but a rising star on the border had already touched Li Linfu's sensitive nerves, and he could be sure that if left unchecked, it would not be long before Wang Zhongsi would become his biggest rival in the court.
However, Wang Zhongsi had no chance, and under the constant slander of Li Linfu, Li Longji was very angry that Wang Zhongsi did not attack the impregnable Stone Fortress City, and angrily demoted him to Hanyang Taishou, and it was not long before Wang Zhongsi died violently in office.
This is just one of the cases in which Li Linfu's crackdown threatened his position, and in his twenty years of ruling, countless rookies with outstanding abilities like Wang Zhongsi were all beaten to death by Li Linfu.
Yang Guozhong rises
However, he did not suppress Yang Guozhong, who was from a mixed background, and Yang Guozhong, who was backed by the Yang sisters, was favored by Li Longji through the relationship of his cousin Yang Yuhuan, and made waves in the court, continuously framed Yang Shenyun and Wang Hao, seized the power of the prime minister, and became Li Linfu's number one opponent.
Within a few rounds of Li Linfu's confrontation with Yang Guozhong, he found that he could no longer defeat this foreign relative who was deeply favored by Li Longji, and he finally fell on the hospital bed in fear.
Although Li Longji created an unparalleled prosperity in the dynasty, it also laid countless disasters for the middle and late Tang Dynasties. The chancellor Zhang said that he personally untied the shackles of power since Li Shimin, Li Linfu shifted the way the imperial court appointed officials from talent selection to seniority, and frantically attacked dissidents, taking away the sword of Shang Fang that was pressed on the head of the border general, Li Longji favored the eunuch Gao Lishi, broke the system formulated by Li Shimin that eunuchs could not serve as sanpin generals, blindly arrogant, unchecked, and allowed all localities to sit in the throne, and finally ushered in Li Tang's biggest disaster: the Anshi Rebellion.
