In the history of China's revolution, the cooperation between Liu Bocheng and Deng Xiaoping fully verified the political ethics of "gentlemen are harmonious but different". Liu and Deng Dou are Sichuanese, but Liu Bocheng was born in 1892 and 1904. There is a big age gap. In revolutionary work, according to the division of labor, Liu Bocheng is responsible for military work and Deng Xiaoping is responsible for political work. But the division of labor is not separated, and the work always supports each other. Liu Bocheng's work attitude is "light over heavy", no matter big or small, everything is respectful; Deng Xiaoping, on the other hand, is "as easy as lifting weights" and treats every major event with a relaxed attitude. But the two never stick to their own views, and no matter which one is right, they will persist in doing it. Liu Deng's unity and cooperation and tacit cooperation have enabled Liu Deng's army to win every battle no matter how difficult it encounters for decades.
