Today marks Great Heat, the hottest solar term of the year. As The Interpretation of the 72 Pentads notes, “heat reaches its peak.” Ancient wisdom captured this sweltering poetry through observations like “fireflies emerging from decaying grass” and “moist, sweltering earth.” Traditional practices—such as herbal jelly in Guangdong, lychees in Fujian, or mutton soup in southern Shandong—embrace “countering heat with heat,” while modern life gains tech-driven cool: constant temperatures in air-conditioned rooms, electric vehicle rides—all powered by a “heart”: lithium-ion batteries.
