This classic of governance embodies 6000 years of ancient Chinese history. It discusses various aspects, from royal cultivation to economic development and building an ideal society. If a king acts arbitrarily, he is gathering disasters, placing himself in a river, desperately swimming towards a sandbar in the water. The strength of people's loyalty is positively correlated with social integrity, the king's relief, and the wealth of the people, and negatively correlated with the square of the distance between the king and the people. When a king possesses power but is cautious enough not to use it, the distance between the king and the people approaches zero, and the strength of the people's loyalty is extremely strong. The king is quiet and inactive, without any achievements, without giving orders or leading the world, aiming to narrow the distance between the king and the people. Along with economic development, social ugliness will also come, like planting vegetables with weeds naturally. The king must not use solid administrative measures to eliminate it. Otherwise, the economy will decline again. By guiding with persuasion and assistance, national governance can conform to nature. Only by imitating nature can the king bring prosperity to the people and strength to the country. Only humans can be liberated from the material constraints of nature. Only by following the example of nature can people thoroughly enjoy freedom and free themselves from the shackles of society?the ultimate realization of the common ideal of human liberty and prosperity. The ideal society of humanity will reappear.
