🚀 开 = open + 展 = unfold/spread; together: open up and spread out
开 means open and 展 means unfold or extend. Combined, 开展 literally reads as open-and-unfold, which extends naturally to launching or developing an activity, exhibition, or campaign.
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'.
