Mencius' gentleman spirit is embodied in Boyi and Shu Qi. Although Boyi and Shu Qi are the sons of Gu Zhujun, they refuse to succeed to the throne and enjoy wealth, which can be regarded as wealth and immorality. Later, when I heard that King Wu was going to crusade against Shang Zhouwang, I flattered him. He is not afraid of power and life and death, which shows that his power is unyielding. After the suppression of the Yin rebellion, the whole world surrendered to the Zhou Dynasty, and Boyi and Shu Qi were ashamed of it, refused to eat and starved to death in shouyangshan. The gentleman spirit advocated by Mencius is the brightest spot of the Chinese nation and has made great contributions to shaping the soul of the nation. Of course, the greatness of China culture is also manifested in four major inventions, poems and songs, music, calligraphy and painting, the Great Wall of the Forbidden City and so on. However, the greatness of China Wenhua is concentrated in the thoughts of its great thinkers. Mencius' gentleman spirit is one of the most precious spiritual wealth in culture, and it will never be out of date in modern society. The state blindly pursues scientific and technological and economic benefits. Individuals blindly pursue power, fame and fortune, eat, drink and be merry, care about people and love things less, their moral consciousness is weakened, and the warmth of the world is less. As a result, there are many disadvantages, which are boring and precarious. Mencius' gentleman personality spirit is of great significance for solving these problems faced by human society.
