Li Linfu is the great-grandson of Tang Gaozu's cousin Changping Wang Shuliang, because of his good pronunciation, he was a low-level official in charge of palace guards and honor guards at first, and then climbed to the high position of prime minister by relying on a set of flattering skills.

After becoming prime minister, he always pretended to be approachable in his dealings with people, making people think that he was a loyal minister.

In fact, he has a poisonous sword hidden in his stomach, which may secretly hurt people at any time. As Sima Guang described in "Zizhi Tongjian": "Li Linfu is the prime minister, and those who want to make meritorious deeds and have strong prestige will force themselves to do everything possible." Especially taboo literary scholars. Or the yang is good with it, and the yin is good, and the yin is deceitful. It is said that Li Linfu has honey in his mouth and a sword in his belly. Zhang Jiuling, who was the same prime minister as Li Linfu at that time, was outstanding in talent and upright as an official.

Li Linfu was jealous of Zhang Jiuling's talent and morality, and always wanted to design to eradicate him. Xuanzong's Concubine Wu Hui loved the harem, and the Shouwang and Sheng Wang were particularly favored, while the crown prince Ying was alienated.

Li Linfu then falsely accused the prince and others of complaining in front of Xuanzong, and formed a party for personal gain, plotting against him. Xuanzong was furious and wanted to abolish the prince and discussed with Zhang Jiuling.

Zhang Jiuling believes that the crown prince is the foundation of the country, grew up in the palace, was taught by His Majesty, and has no fault, and the emperor cannot abolish him because of his own joy and anger.

After Xuanzong heard this, he was greatly displeased. Li Linfu was present without saying a word, but later said in front of Xuanzong's favored eunuchs: "Why do you need to discuss royal matters with others. The implication is that Zhang Jiuling stretches out his hand too long and is nosy.

These words soon reached Xuanzong's ears, and Xuanzong also felt that Zhang Jiuling was too arbitrary, and Li Linfu took the opportunity to say a lot of bad things about Zhang Jiuling in front of Xuanzong.

In 736 A.D., Xuanzong wanted to promote the Shuofang Festival to make the ox cyclamen. Zhang Jiuling said: "The border general trains soldiers and horses, saves military resources, this is the work of the division, Your Majesty should reward him, and if you want to give him food, it is not appropriate." Xuanzong was speechless, and Li Linfu did not speak at the time, but when he came back, he told Niu Xianke what he said.

The next day, Niu Xianke saw Xuanzong and gave up the official title in tears. Xuanzong still wanted to seal the cattle cyclamen, and Zhang Jiuling argued for it.

Xuanzong was very angry and said, "Is it always up to you to decide everything? Zhang Jiuling said that this is his own business, and Niu Xianke was originally born as a small official, and it is inappropriate to be promoted to prime minister because he is illiterate, Li Linfu later secretly said to Xuanzong: "The Son of Heaven employs people, why not?" Zhang Jiuling is just a civil official, sticking to the ancient meaning, not knowing the general situation, and not being able to become a great tool. Xuanzong was even more unhappy because of this.

Zhang Jiuling had a close relationship with Yan Ting, a Chinese scholar, and Yan Ting's ex-wife married Wang Yuanyan, the assassin of Ulzhou, after the divorce.

It happened that Wang Yuanyan was accused of guilt, and Xuanzong ordered Yan Ting to wait for an investigation, and Yan Ting absolved Wang Yuanyan of his crime. Xuanzong thought that Yan Ting and Wang Yuanyan had a personal relationship, and Zhang Jiuling thought that Yan and Wang had no selfish relationship.

Xuanzong linked the previous events to this incident, believing that Zhang Jiuling had formed a party and finally removed him from the post of prime minister.

Li Linfu framed Zhang Jiuling, and finally achieved his goal and served as the secretary of the order on behalf of Zhang Jiuling.

In business, gentleness, gentleness, and submissiveness can not only conceal plots and secretly prepare, but also make tough, stern, superior and confident competitors ignorant and take them lightly, and finally have to treat the winner's smile with anger and chagrin.
