📝🏫 考 test + 场 field = the field where you get tested
场 originally meant an open ground or threshing floor, then extended to any venue. Pair it with 考 (test) and you get the specific venue where exams are held.
考 — old 老 (top) + 丂 phonetic
Originally written like 老 ('old'), 考 depicted an elderly person with long hair leaning on a cane, and the two characters were once interchangeable. Over time 考 specialized to mean 'deceased father' and later 'to examine, test, investigate,' with the bottom 丂 hinting at the sound.
场 — earth 土 + 昜 (bright/rising)
Originally a flat open ground used for sun-drying grain or for ritual offerings, hence 土 'earth' as the meaning component. 昜 supplies the sound and hints at an open, sunlit space. The meaning broadened to any open area or venue, and as cháng it still refers to a threshing floor or a session/spell of something.
