Im Sang-ok (Korean: 임상옥; Hanja: 林尙沃; 1779–1855) was a trader in the mid-Joseon period.
His bongwan is Jeonju, courtesy name is Gyeongyak (경약; 景若), art name is (가포; 稼圃).
Because ginseng from Joseon was popular during the Qing dynasty and the Chinese paid a lot for it, Im smuggled it to them.
She found Im and gave him ten times of money he spent for buying her.
One day Chinese merchants became jealous of Im right to sell ginseng, so they boycotted him to force him to further lower the price.
In response, Im burned his ginseng in his yard and called the Chinese merchants.
