谷（gu）
Name meaning
谷 (gu) means valley and also grain. In names it can suggest fertile depth, shelter, humility and a space where life gathers.
Practical naming use
谷 (gu) is a grounded nature character. It is not showy; its strength is depth, fertility, quiet protection and the ability to hold water, wind and grain. In a modern name it works for someone meant to feel patient, inwardly spacious and connected to land or learning rather than display.
Pair 谷 (gu) with light, peace or learning: 谷明 (Guming), 谷安 (Guan), 谷文 (Guwen) or 谷宁 (Guning). Avoid another earth-heavy character if the name becomes too still.
谷明 (Guming): Gu contributes valley, grain; Ming adds brightness, clarity.
