Why does Trump call him "Knowing King"?

Because of his series of behavioral characteristics. The so-called "knowing the king" refers to Trump's habit of speaking freely in front of all kinds of media. No matter what topic he talks about, after talking eloquently, he will inevitably add the sentence, "No People know XXX better than me." Donald Trump, born in New York, USA, originally from the Free State of Bavaria, Germany, is a German-American political and party politician, entrepreneur, real estate businessman, television personality, and the 45th President of the United States (January 20, 2017 - January 20, 2021). During Trump's administration, he made great progress in tax cuts, tough trade policies, increased diplomatic and military deployment, and loosened financial supervision through legislation, executive orders, and personnel appointments. Among them, tax reform was his early achievement. The biggest highlight.
