Therefore, I think that Emperor Wanli is not really regardless of state affairs, but a brilliant behind-the-scenes ambassador. Even if he doesn't go to court, he can know what happened in North Korea. This is well documented evidence, because during the reign of Emperor Wanli, the cabinet system was implemented, and the DPRK-China affairs and power were basically in the hands of cabinet ministers. Moreover, the emergence of the two generals, Qi Jiguang and Li, is also inseparable from the support behind them, and there is actually a reason why he did not go to court. At that time, there were many political parties in North Korea, which suppressed each other and seriously interfered in North Korea. At that time, Zhu Yijun, the emperor of Wanli, thought a lot of ideas to benefit the country and the people, but he was always obstructed by courtiers in every way, which hit his self-confidence and made him upset at once. He was sick in his heart, so he chose not to see these ministers again, so he didn't have to have these troubles suddenly. But it's not a bad king.
