Because, before the Warring States period, the emperor was called "Wang" and the vassal was called "Gong", and only Zhuan Xu, Kun, Yao and Shun were called "Emperor" after their death. In other words, these legendary figures' way of governing the country is the "imperial way", which is also commonly known as the "Huang Lao" theory, and the core is to learn from nature.

Overbearing means that legalism is the core of internal heavy punishment and foreign militarism.

The kingly way is mainly put forward by Confucianism, which requires the king to implement "benevolent government" to the people and make them "near and far away", which is called "kingly way"

The study of Huang Lao is the general name of Huangdi School and Laozi School. In addition to the study of Zhuangzi, it is the largest branch of Taoism, and the school's thoughts are masculine [1]? From the mid-Warring States Period to the Qin and Han Dynasties, Taoism between Huang and Lao was popular, with rich theory and strong sense of reality. This school respects the legendary Huangdi and Laozi as its founders.

As a philosophical thought, the skill of Huang Lao was formed in the Eastern Zhou Dynasty and the Warring States Period. However, as a widely circulated social trend of thought, it was in Qi State in Wei and Jin Dynasties. The representative figures of this school highly praised the thoughts of Huangdi and Laozi, took Taoism as the main idea, and adopted the views of Yin and Yang, Confucianism, Legalism and Mohism.

The ideological development of the Huang-Lao School is mainly divided into two themes: technical invention and political thought. Based on the metaphysical ontology of Tao, it combines physical health preservation, folk skills, mathematical skills, art of war, strategy and so on, and has a strong purpose and operability.

In the west, Huang is often called "teleology" or "instrumental Daoism".

From the content point of view, the skill of Huang Lao inherits and develops the "Tao" thought of Huang Di and Lao Zi. They believe that "Tao" exists as an objective necessity, and point out that "everything is the same, and constancy stops" and "everyone uses it without seeing its shape". ? In the social and political field, Huang Laozhi emphasized "Tao gives birth to law".

It is believed that the monarch should "govern by doing nothing", "save important things, save taxes, not seize people's time", "be impartial", "humble and simple" and "be gentle and keep a wife", and achieve "promising" through inaction. ?

The above thought had a certain influence in the early Han Dynasty, which led to the flourishing age of "the rule of culture and scenery" in the history of China. In the Eastern Han Dynasty, the combination of Huang Lao's skill and the new divination theory gradually evolved into a natural way of longevity, which had a great influence on the formation of Taoism.
