As early as when Zhu Youxiao was not a prince, Wei Zhongxian specially served their mother and son. In addition, the Hakkas "opposite to Wei Zhongxian" are Zhu Youxiao's wet nurses, which created convenient conditions for Wei Zhongxian's promotion step by step. After Zhu Youxiao succeeded to the throne, Wei Zhongxian immediately became a popular figure in North Korea.
In order to expand his influence, Wei Zhongxian, with the support of Hakkas, first attacked Wei Chao, the powerful minister, and then Xizong also sided with his wet nurse Hakka and Wei Zhongxian. Wei Chao was forced to report illness and left the palace to be besieged, and was driven to Fengyang. After Wei Chao left the palace, Wei Zhongxian sent a killer to poison him on his way to Fengyang. From then on, almost all the power in the DPRK fell to Wei Zhongxian and the Hakkas, who later named him "Nine Years Old".
After destroying his political enemies, Wei Zhongxian's next step is to control the platform and become "nine years old".
Xizong has a soft spot for carpentry and disdains state affairs. Wei Zhongxian reported this letter to Zong when he was absorbed in carpentry. Everything Wei Zhongxian did almost satisfied Zong, so Zong Yue came to trust him more and more.
Later, Xi Zong put Wei Zhongxian on an equal footing with him. Even among the people, there are many people who only know that there is Wei Zhongxian in the imperial court, but they don't know that there is another Sect. Wei Zhongxian called himself "nine years old" when he saw that the time had come.
