This sentence is a famous saying of Xun Kuang.

Xun Kuang was a thinker at the end of the Warring States Period. Also known as Sun Qing and Zhao Guoren. Zeng San offered wine to Xia Ji and Gong Xue in Qi State, and later served as the Lanling Order in Chu State. There is a copy of Xunzi handed down from generation to generation.

3. Xun Kuang is in an era when the feudal landlord class unified the country. In order to meet the needs of the emerging landlord class, he critically absorbed the ideological achievements of the pre-Qin philosophers and established a complete theoretical system, which had a great impact on the feudal society after the Han Dynasty.

4. Xun Kuang advocates the goal of enriching the country on the basis of enriching the people and achieving "top-down wealth". He believes that agriculture must be developed to enrich the country's income and reserves, and its fundamental strategy is to "open up sources" and "save streams". The source is agricultural production, and the flow direction is national finance. Xun Kuang emphasized the important role of the national financial policy of enriching the people in developing agricultural production. He advocated that the state should adopt a light tax policy to meet the basic needs of ordinary people, so as to improve their enthusiasm for production and promote the development of agriculture. Xun Kuang's fiscal principle of increasing revenue and reducing expenditure had a far-reaching impact on China's financial thought in feudal society.
