to take care
👀 关 concern + 照 shine a light on = keep watch over and look after someone
关 — door 门 + simplified 关 inside
关 is the simplified form of 關. The traditional character showed a gate (門) with a bolt or crossbar inside, depicting a barred door — hence 'to close' or 'shut'. Meaning later extended to 'pass' (a guarded gate), 'barrier', and figuratively 'concern' or 'connection'.
照 — 昭 (bright) phonetic + 灬 (fire radical)
照 is a semantic-phonetic compound. The bottom 灬 is a variant of 火 'fire', giving the meaning of light or illumination, while 昭 'bright' on top supplies the sound 'zhào' and reinforces the brightness sense. It originally meant to shine light on something, later extending to 'reflect', 'photograph', and 'according to'.
