召开
zhàokāi · HSK 4
convene
📢 召 = summon/call + 开 = open; literally 'call open' = convene a meeting
召 (zhào) means to summon or call together; 开 (kāi) means to open or start. Together 召开 means to call together and open — i.e. convene or convoke a meeting, conference, or assembly.
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'.
