I have the following etymology from Outlier Dictionary of Chinese Characters:
勤 qín is composed of 堇 jǐn “a type of ancient punishment in which fire was used to dry a person out” and 力 “force, power, effort,” pointing to the original meaning “toil, labor.”
my question is this punishment killing the person with fire? or make him sit near fire to dry up? Please explain high level this punishment to understand the character better. thanks
