With Yongzheng's favor, he became arrogant and arrogant, acting in collusion with others, making Yongzheng wary, and his attitude towards him began to change. When he was suppressed, Yongzheng used the topic to think that he was arrogant, ignored the emperor, took back his power and transferred him to Hangzhou. In addition, he was beaten by officials and exposed the crime. Yongzheng naturally punished him.
Moreover, in order to prevent Yongzheng from having doubts about himself, Rob can't immediately find the trace of hiding Dandan and break it. He can only point out the way for him through Wu Sidao as a reason to send troops. At that time, everyone knew that Wu Sidao had never been to the northwest. So it was in this case that Nian Gengyao sent troops to crusade, but he didn't choose to kill Rob Tenzin, but let him go quietly, because he knew that Rob Tenzin would want to make a comeback as long as he was alive, so his position would naturally not be affected by this matter.
He asked Rob to hide Tenzin, so that Yong Zhengdi could continue to trust himself, his position could be stabilized, and he could continue to be a general. Make sure you are successful all your life.
