Tips
culture
4th of the 24 solar terms (二十四节气). Falls on March 20 or 21. Marks the midpoint of spring when the sun crosses the celestial equator heading north. 分 means 'to divide' — day and night are divided equally.
memory
春 (spring) + 分 (divide) = the day that divides spring in half. Parallel to 秋分 (Autumn Equinox) — same idea, opposite season.
