OSHANIN:1) проводить воду (каналом); углублять; дренажировать; 2) извлекать, вытаскивать; обирать
Комментарии:Also used for a homonymous toponym (thus in Shi 32,3). Modern jùn is secondary (under the influence of 俊竣畯 etc.). Since Late Zhou the character is attested with the meaning 'to ladle out, take from' which seems to be archaic (judging by the external evidence); perhaps 'deep, profound' < 'scoopable' (?).
