Use formality to rule a country, use the odds and tricks to command the war, and use inaction to win the state. Why do I know this conclusion? Because there are too many taboos in society, people can be even poorer, there are too many means of getting profit for the people, the country grow awkward, The more people have skills, the more treasures will be. The more regulations, the more people will become criminal. Therefore, the saints said that if I am inaction, the people will evolve themselves. If I stay quiet, it will make the people adjust themselves. If I don't launch a project, it will make the people get rich. if I don't have the desire, it will make the people themselves simple.
