"The Official Classic" conducts the most in-depth, detailed, sober and intelligent study of China's old officialdom. It lists the wisdom, strategies and abilities that officials in ancient times should have in an all-round and multi-angle manner, and is of value to people today. Re-reading official scriptures and understanding the survival rules of ancient elites will be of great help to our personal behavior and career today. The real legacy left to the future by the "Official Classic" is not the specific articles, but three meta-abilities: the wisdom of dynamic balance - such as the dialectics revealed by "combining leniency with severity"; long-term thinking - such as "politics have perseverance" to combat short-termism; human insight - such as "knowing people and bringing peace to the people" beyond the worship of the system.
