What's the vendetta between Zhang Yuting and Nian Gengyao? Why do you want to kill Nian Gengyao?

Speaking of the deep hatred between Zhang and Nian Gengyao during the Yongzheng period, there is only one thing, that is, Nian Gengyao indirectly harmed Zhang's only good friend Sun Jiacheng. And the reason why Zhang wanted to kill Nian Gengyao was not only to avenge Sun Jiacheng, but also because Nian Gengyao was too arrogant and did a lot of illegal things in private. As an important official of the Qing Dynasty, Zhang certainly would not sit idly by.

First of all, let's talk about the only problem between Zhang and Nian Gengyao, namely the Sun Jiacheng incident. In those days, Nian Gengyao was well treated by Yong Zhengdi because of his great contribution. Nian Gengyao became arrogant after he got the biggest umbrella in the world. Not only did he put on airs in the capital, but he always bullied the civil servants in the court, which made Sun Jiacheng's ministers very unhappy. Sun Jiacheng took the lead in impeaching Nian Gengyao. But let Yong Zhengdi notice the official position of Sun Jiacheng school.

After learning that Sun Jiacheng impeached himself, Nian Gengyao tried every means to defend himself. In the end, Sun Jiacheng's impeachment failed, and he was sent to the frontier. Zhang, who was withdrawn, had no good friends in the imperial court, but Zhang had been involved in a case earlier because Sun Jiacheng helped him get away safely, and Zhang appreciated Sun Jiacheng's talent very much, so Zhang and Sun Jiacheng became bosom friends. After Sun Jiacheng was sent, Zhang became more dissatisfied with Nian Gengyao.

After Sun Jiacheng was sent to the frontier for impeaching Nian Gengyao, not only the DPRK ministers were very afraid of Nian Gengyao, but Nian Gengyao, who was already very domineering, was even more unscrupulous. What's more, Nian Gengyao secretly took money to sell officials, which made loyal minister Zhang unbearable. So Zhang collected Nian Gengyao's evidence and joined forces with his ministers to impeach Nian Gengyao, with the aim of completely overthrowing Nian Gengyao and his henchmen.
