heaped up earth becomes a mountain(tǔ rǎng xì liú)

heaped up earth becomes a mountain

Soil: soil; rill: River. It's a metaphor for small things. It also means that although things are very subtle, they can play a huge role by accumulating. [source] biography of Li siliezhuan in historical records: "it is the Taishan mountain that does not allow the earth to grow, so it can become large; the river and sea do not choose the small flow, so it can be deep."
