"The Complete Works of Thousand Black Studies" is actually a must-learn leadership philosophy in life and is the representative work of Mr. Li Zongwu. In the book, he preaches that one should have a face as thick as a city wall and a heart as black as coal, so that one can become a "hero." He cited Cao Tuo, Liu Bei, Sun Quan, Sima Yi, Xiang Yu, Liu Bang and other figures as examples, trying to prove his thick and black knowledge and listed how the thick and thin of each person affected their success or failure. There are three steps to learning Kung Fu in thick black. The first step is "thick as a city wall, black as coal". Although the city wall is thick, it can be blasted through with artillery. Although the coal is black, its color is abominable and no one wants to get close to it; the second step is "thick and hard, black and bright". Although there is a world of difference between synchronized kung fu, Ding is tangible and colored after all, and others can see clues after careful observation; the third step is "thick and invisible, black and colorless", entering the realm of "silent and odorless, invisible and colorless". Once you reach this state, you can be invincible, invincible, unstoppable, and invincible. The thick black art was regarded as a standard by feudal politicians, and it was a clever trick for them to fight for power and gain. Divisive politicians may not necessarily understand political science, but they must understand thick and black science.
