open
🏪 kai = open + she = set up → open-set a new shop or course
开 means open, 设 means set up or establish. Together they form the act of opening and setting up something new — whether launching a storefront or offering a class for the first time.
开 — two hands 廾 + door 门 (open gate)
Originally written 開, showing two hands (廾) lifting the bar (一) off a gate (門) to open it. The simplified form 开 keeps the two-hands element and drops the gate. Core meaning 'to open' extended to 'start, operate, bloom'.
设 — speech 讠 + hand holding tool 殳
设 combines 讠 (speech) with 殳 (a hand wielding a tool or weapon), suggesting giving orders to set something up. The original sense was to arrange or establish through command, which extended to today's meanings of 'set up,' 'design,' or 'suppose.'
