1. The Warring States Period Laozi "Laozi": Great things in the world must be done in detail.

All major events in the world are formed step by step from small places.

2. Qin Dynasty Li Si's "Book of Remonstrance and Chasing Guests": Mount Tai does not allow soil, so it can become as big as possible; rivers and seas do not allow small streams, so they can become as deep as possible.

Mount Taishan does not allow soil, so it can achieve its height; rivers and seas do not pick on small water flows, so it can achieve its profoundness.

3. Pre-Qin Han Fei's "Han Feizi·Yu Lao": A thousand-foot embankment collapses in the ant nest, collapsed by the ant nest; a hundred-foot room is burned by the smoke from the gap.

A thousand-mile-long embankment may collapse in an ant's cave because there are ants digging holes; a hundred-foot-tall building may collapse due to sparks emitting from the gaps in the chimney, causing a fire. Burn.

4. Zhao Shenzi's "Shenzi Zhizhong": "Therefore, the material of the corridor and temple is not the branch of a tree; the pure white fur is not the skin of a fox."

So the materials of the imperial court cannot be made from a tree branch; the pure white clothes cannot be pieced together from the skin of a fox.

5. The Warring States Period Zisi's "The Doctrine of the Mean": To achieve the broad and subtle.

Achieve a broad and broad realm while also going deep into the subtleties.
