Sun Jiacheng was a loyal courtier, a slanderous courtier, and a direct courtier. It should also be noted that Sun Jiacheng is still a clever courtier. It should be said that without Sun Jiacheng, Nian Qianyao's arrogant style would also be impeached, and there would be no good results, Sun Jiacheng was just a lead, a cannon battle that took the lead in firing. Yongzheng is of course smarter, but he is rational. From the time he sat in front of Nian Qiuyue and shouted "remove his armor, take off, take off, take off" until Qiu Yue finished taking off and then left again, he knew that Yongzheng had already seen Nian Tangyao.
Sun Jiacheng was grateful for Yongzheng's kindness, and he also fulfilled his duties in the Metropolitan Inspection Yuan, and he also stepped forward to lead the officials to impeach the culprits, but also visited Zhang Tingyu late at night, persuading him to petition for guilt and support the murder of his younger brother Zhang Tingyu, which not only showed Sun Jiacheng's loyalty, but also brought forward his humane side, after all, Zhang Tingyu was kind to him at that time, if Zhang Tingyu did not express his position at this critical moment, he would inevitably plant a thorn in Yongzheng's heart!
Although there is a festival with Nian Qianyao, Sun Jiacheng may have the difficulty of considering working with Nian Qianyao, flashing "only know what not to do" in an instant, and more is to consider how to complete his job. The so-called knowing that it was a dead end was that Sun Jiacheng was thinking about his own safety, which was obviously inconsistent with the personality of his direct subjects, and was not the main focus of his consideration. It can also be said that if Sun Jiacheng considers too many personal gains and losses, he will not have the image of a direct subject who is not afraid of power.
Sun Jiacheng gladly went to Nian Qianyao to assist in the implementation of the new policy, mistakenly believing that Nian Qianyao was dead and did not dare to move him, and then carried out reforms in his capacity as a minister of Chincha. However, I didn't expect that Nian Qianyao actually started to do it, which can also be regarded as Sun Jiacheng's mistake. But all this is in Yongzheng's plan, and Sun Jiacheng is just a pawn for him. When Sun Jiacheng died, Yongzheng had ironclad evidence of dealing with Nian Tangyao.
