Left radical is
a character found only in Chinese, meaning 'plow'. Right radical is
'hair' (毛), which here acts phonetically to express 'not/cease to be'.
This character originally referred to a failed crop. Henshall
suggests taking the left radical as a 'heavily branched tree' (木), and
mnemonic: 'Heavily branched tree wastes away to hairs.'
