Major Heat — Born Hour

Major Heat: the folk heat peak of the year, deep inside Wei month.

Overview

Da Shu (大暑) is Wei month's Zhong Qi at 120°. Residual summer fire sits in thick earth climate.

Pentads: 腐草为萤、土润溽暑、大雨时行. Thunderstorms and humidity characterize many regions.

Customs: drinking 伏茶, eating 仙草 (grass jelly) in Guangdong/Taiwan, '送暑' rites in some villages.

One month command (Wei) covers both Xiao Shu and Da Shu — heat names do not switch pillars.

Deepens 未 month.

Culture Custom

Grass jelly (烧仙草) and mung bean soup are regional summer foods tied to heat coping, not medical claims.

Three pentads: fireflies from grass; steamy earth; timely rains.

Classical: great heat is the extreme of summer warmth.

Month command: Wei mid-point; fire and earth saturate.

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