高峰期
gāo fēng qī · HSK 7
peak period
⛰️📈 高 (high) + 峰 (peak/summit) + 期 (period) = high-peak period
高 means high, 峰 means mountain peak or summit, and 期 means a fixed period or phase. Together they name the stretch of time when activity reaches its summit — rush hour on roads, peak season for travel.
高 — pictograph of a tall building/tower
高 is a pictograph of a tall structure, likely a watchtower or multi-story gate, with a roof on top, an upper chamber, and a base below. From this concrete image of height it extended to the general meanings 'tall,' 'high,' and figuratively 'lofty' or 'noble.'
期 — 其 (phonetic) + 月 (moon/time)
期 is a phono-semantic compound. The right side 月 (moon) signals meaning, since lunar cycles marked fixed time periods in ancient China. The left side 其 supplies the sound. Together it points to a set time, period, or appointed date — meanings still carried today in words like 期间 and 日期.
