Grain Rain — Born Hour

Grain Rain closes the spring sequence: rain for grain, earth fully engaged before summer fire.

Overview

Gu Yu (谷雨) is the Zhong Qi of Chen month at 30°. Agrarian calendars treat it as the last generous rain of spring sowing weather.

Pentads: 萍始生、鸣鸠拂其羽、戴胜降于桑. Peach blossom festivals and tea picking (谷雨茶) peak in many provinces.

Structure: deep wet earth inside a wood-strong month — a bridge toward Si month fire at Li Xia. No month-branch switch.

Reading tip: 'spring' as a slogan does not make wood strong; month command, roots and moisture still decide.

Culture Custom

Gu Yu tea (雨前茶) is prized for tender leaves before summer heat — food culture, not elemental medicine.

Three pentads: duckweed; doves preen; hoopoes on mulberry.

Classical: rain nourishes the hundred grains in the third month.

Month command: Chen mid-point; last spring rain before summer fire.

Jie nodes can move the Month Pillar; Zhong Qi deepen the same month without switching branch.

Grain Rain is a calendrical node and cultural festival, not a weather guarantee or personal luck verdict.
