Radical 工

5 strokes

left hand (53a) + work 工 (147) = left 左

This means the left-hand side, on the left, etc. (rather than the actual hand with fingers).

[左边 (41) zuǒbiān left-hand side]

[左手 (31) zuǒshǒu the left hand]

(Showing a new employee how to work the big machine in the factory) “Use your left hand, your wedding ring hand, to work the controls as they are all on the left side of the machine.” / [DIY pronunciation]
